[ Upstream commit aeff09276748b66072f2db2e668cec955cf41959 ]
The available (i.e. not used) buffers are returned by stk1160_clear_queue(),
on the stop_streaming() path. However, this is insufficient and the current
buffer must be released as well. Fix it.

[ Upstream commit 80ccf4ad06dc9d2f06a8347b2d309cdc959f72b3 ]
img_ir_remove() passes a pointer to the ISR function as the 2nd
parameter to irq_free() instead of a pointer to the device data
structure.
This issue causes unloading img-ir module to fail with the below
warning after building and loading img-ir as a module.

[ Upstream commit 0e661006370b7e7fb9ac9d94f9c3500a62cd559b ]
Stopping the vb2 thread (as used by several DVB devices) can result
in an 'UNBALANCED' warning such as this:
vb2: counters for queue ffff880407ee9828: UNBALANCED!
vb2: setup: 1 start_streaming: 1 stop_streaming: 1
vb2: wait_prepare: 249333 wait_finish: 249334
This is due to a race condition between stopping the thread and
calling vb2_internal_streamoff(). While I have not been able to deduce
the exact mechanism how this race condition can produce this warning,
I can see that the way the stream is stopped is likely to lead to a
race somewhere.
This patch simplifies how this is done by first ensuring that the
thread is completely stopped before cleaning up the vb2 queue. It
does that by setting threadio->stop to true, followed by a call to
vb2_queue_error() which will wake up the thread. The thread sees that
'stop' is true and it will exit.
The call to kthread_stop() waits until the thread has exited, and only
then is the queue cleaned up by calling __vb2_cleanup_fileio().
This is a much cleaner sequence and the warning has now disappeared.

[ Upstream commit 8e48a2d54c5d74ea3e9dc4c3b9037786bb447f36 ]
Unlike scan_async_group(), soc_of_bind() doesn't allocate its
soc_camera_async_client structure using devm_kzalloc(), but has it
embedded inside the soc_of_info structure. Hence on failure, it must
free the whole soc_of_info structure, and not just the embedded
soc_camera_async_client structure, as the latter causes a warning, and
may cause slab corruption:

commit 983c5bd26b86ba1c0d79b770e596bb8b77e42f32 upstream.
Since commit da6e162d6a46 ("[media] rc-core: simplify sysfs code"), when
the IR protocol is set using the sysfs interface to the same set of
protocols that are already set, store_protocols() does not refresh the
scancode filter with the new protocol, even if it has already called the
change_protocol() callback successfully. This results in the filter
being disabled in the hardware and not re-enabled until the filter is
set again using sysfs.
Fix in store_protocols() by still re-applying the filter whenever the
change_protocol() driver callback succeeded.
The problem can be reproduced with the img-ir driver by setting a
filter, and then setting the protocol to the same protocol that is
already set:
$ echo nec > protocols
$ echo 0xffff > filter_mask
$ echo nec > protocols
After this, messages which don't match the filter were still being
received.

commit a8f29e89f2b54fbf2c52be341f149bc195b63a8b upstream.
Userspace expects to see a long space before the first pulse is sent on
the lirc device. Currently, if a long time has passed and a new packet
is started, the lirc codec just returns and doesn't send anything. This
makes lircd ignore many perfectly valid signals unless they are sent in
quick sucession. When a reset event is delivered, we cannot know
anything about the duration of the space. But it should be safe to
assume it has been a long time and we just set the duration to maximum.

commit 6cf11ee6300f38b7cfc43af9b7be2afaa5e05869 upstream.
The locking scheme inside the vb2 thread is unsafe when stopping the
thread. In particular kthread_stop was called *after* internal data
structures were cleaned up instead of doing that before. In addition,
internal vb2 functions were called after threadio->stop was set to
true and vb2_internal_streamoff was called. This is also not allowed.
All this led to a variety of race conditions and kernel warnings and/or
oopses.
Fixed by moving the kthread_stop call up before the cleanup takes
place, and by checking threadio->stop before calling internal vb2
queuing operations.

commit ac03086067a5524ae9e020ba5712a208c67b2736 upstream.
The end timer is used for switching back from repeat code timings when
no repeat codes have been received for a certain amount of time. When
the protocol is changed, the end timer is deleted synchronously with
del_timer_sync(), however this takes place while holding the main spin
lock, and the timer handler also needs to acquire the spin lock.
This opens the possibility of a deadlock on an SMP system if the
protocol is changed just as the repeat timer is expiring. One CPU could
end up in img_ir_set_decoder() holding the lock and waiting for the end
timer to complete, while the other CPU is stuck in the timer handler
spinning on the lock held by the first CPU.
Lockdep also spots a possible lock inversion in the same code, since
img_ir_set_decoder() acquires the img-ir lock before the timer lock, but
the timer handler will try and acquire them the other way around:

checks before updating the timer.

del_timer_sync() call. The timer is prevented from restarting before the
lock is reacquired by a new "stopping" flag which img_ir_handle_data()
checks before updating the timer.

commit ea0de4ec5489da0fe738b274effac4f950e93d76 upstream.
A problem was found on Polaris where if the unit it booted via the power
button on the infrared remote then the next button press on the remote
would return the key code used to power on the unit.
The sequence is:
- The polaris powered off but with the powerdown controller (PDC) block
still powered.
- Press power key on remote, IR block receives the key.
- Kernel starts, IR code is in IMG_IR_DATA_x but neither IMG_IR_RXDVAL
or IMG_IR_RXDVALD2 are set.
- Wait any amount of time.
- Press any key.
- IMG_IR_RXDVAL or IMG_IR_RXDVALD2 is set but IMG_IR_DATA_x is
unchanged since the powerup key data was never read.
This is worked around by always reading the IMG_IR_DATA_x in
img_ir_set_decoder(), rather than only when the IMG_IR_RXDVAL or
IMG_IR_RXDVALD2 bit is set.

The cause is that uvc_status_cleanup() is called after usb_put_*() in
uvc_delete(). usb_put_*() removes the sysfs parent and eventually
removes the children recursively, so the later device_del() can't find
its sysfs. The fix is simply rearrange the call orders in
uvc_delete() so that the child is removed before the parent.

commit 2279948735609d0d17d7384e776b674619f792ef upstream.
This patches fixes an ancient bug in the dvb_usb_af9005 driver, which
has been reported at least in the following threads:
https://lkml.org/lkml/2009/2/4/350
https://lkml.org/lkml/2014/9/18/558
If the driver is compiled in without any IR support (neither
DVB_USB_AF9005_REMOTE nor custom symbols), the symbol_request calls in
af9005_usb_module_init() return pointers != NULL although the IR
symbols are not available.
This leads to the following oops:

The prefered fix would be to convert the whole IR code to use the kernel IR
infrastructure (which wasn't available at the time this driver had been created).
Until anyone who still has this old hardware steps up an does the conversion,
fix it by not calling the symbol_request calls if the driver is compiled in
without the default IR symbols (CONFIG_DVB_USB_AF9005_REMOTE).
Due to the IR related pointers beeing NULL by default, IR support will then be disabled.
The downside of this solution is, that it will no longer be possible to
compile custom IR symbols (not using CONFIG_DVB_USB_AF9005_REMOTE) in.
Please note that this patch has NOT been tested with all possible cases.
I don't have the hardware and could only verify that it fixes the reported
bug.

The cx23885 driver still used sg++ instead of sg = sg_next(sg). This worked with
vb1 since that filled in the sglist manually, page-by-page, but it fails with vb2
which uses core scatterlist code that can combine contiguous scatterlist entries
into one larger entry.
This bug led to the following crash as reported by Mariusz:

The IRQs have to be acknowledged before they are serviced, otherwise some events
may be skipped. Also, acknowledging IRQs just before returning from the handler
doesn't leave enough time for the device to deassert the INTx line, and for
bridges to propagate this change. This resulted in twice the IRQ rate on ARMv6

The Tevii S480 outputs 18V on startup for the LNB supply voltage and does not
automatically power down. This blocks other receivers connected
to a satellite channel router (EN50494), since the receivers can not send the
required DiSEqC sequences when the Tevii card is connected to a the same SCR.
This patch switches off the LNB supply voltage on initialization of the frontend.

commit da6e162d6a4607362f8478c715c797d84d449f8b ("[media] rc-core:
simplify sysfs code").
The regression comes from adding function change_protocol in ir-raw.c.
It changes behaviour so that only the protocol enabled by driver's
map_name will be active after registration. This breaks user space
behaviour, lirc does not get key press signals anymore.
Enable lirc protocol by default for ir raw decoders to restore original
behaviour.

If power management is disabled these functions become unused, so there
is no reason to build them. This fixes a couple of build warnings when
PM(_SLEEP,_RUNTIME) is not enabled.

The PLAT_S5P Kconfig symbol was removed in commit d78c16ccde96
("ARM: SAMSUNG: Remove remaining legacy code"). However, there
are still some references to that symbol left, fix that by
substituting them with ARCH_S5PV210.

check in vm_iomap_memory()
When user requests V4L2_MEMORY_MMAP type buffers, the videobuf-core
will assign the corresponding offset to the 'boff' field of the
videobuf_buffer for each requested buffer sequentially. Later, user
may call mmap() to map one or all of the buffers with the 'offset'
parameter which is equal to its 'boff' value. Obviously, the 'offset'
value is only used to find the matched buffer instead of to be the
real offset from the buffer's physical start address as used by
vm_iomap_memory(). So, in some case that if the offset is not zero,
vm_iomap_memory() will fail.
