rc_unregister_device already calls rc_free_device to free the passed device. But in one of ttusbir's probe fail paths, we call rc_unregister_device _and_ rc_free_device. This is wrong and results in a double free. Instead, set rc to NULL resulting in rc_free_device being a noop.

2013-03-23[media] rc-core: don't treat dev->rc_map.rc_type as a bitmapDavid Härdeman
store_protocols() treats dev->rc_map.rc_type as a bitmap which is wrong for two reasons. First of all, it is pretty bogus to change the protocol type of the keymap just because the hardware has been asked to decode a different protocol. Second, dev->rc_map.rc_type is an enum (i.e. a single protocol) as pointed out by James Hogan <james.hogan@imgtec.com>. Fix both issues by introducing a separate enabled_protocols member to struct rc_dev. Signed-off-by: David Härdeman <david@hardeman.nu> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

Some imon devices (like 15c2:0036) need a higher delay between send_packet calls. Default value is still 5ms to avoid regressions on already working hardware.

Even if bus is not hot-pluggable, the devices can be unbound from the driver via sysfs, so we should not be using __exit annotations on remove() methods. The only exception is drivers registered with platform_driver_probe() which specifically disables sysfs bind/unbind attributes. Similarly probe() methods should not be marked __init unless platform_driver_probe() is used.

2013-01-11ARM: OMAP2+: Disable code that currently does not work with multiplaformTony Lindgren
We still need to fix up few places for multiplatform support, but that can proceed separately. Fix the issue by making the problem drivers depends !ARCH_MULTIPLATFORM for now. The remaining pieces that are not multiplatform compatible for omap2+ SoCs are: 1. Some drivers are using custom omap_dm_timer calls There are two drivers that are directly usign omap hardware timers for PWM and DSP clocking: drivers/media/rc/ir-rx51.c and drivers/staging/tidspbridge/core/dsp-clock.c. These can be fixed for multiplatform by allowing a minimal set of hardware timers to be accessed, and for some functionality by using the hrtimer framework. 2. Hardware OMAP4_ERRATA_I688 needs to be fixed up This can't be enabled for multiplatform configurations in it's current form. It may be possible to fix it up to do instruction replacement early on during init. Luckily it looks like this errata does not seem to get hit with mainline kernel code alone at least currently. 3. Legacy header needed for omap-sham.c Looks like it still needs mach/irqs.h for omap1 that does not exist for multiplatform systems. Just ifdef it for now. 4. Mailbox is waiting to get moved to drivers Disable it for now to avoid adding a dependency to the mailbox patches.

2012-12-27[media] media/rc: fix oops on unloading module rc-coreKonstantin Khlebnikov
During modiles initialization rc-core schedules work which calls request_module() several times to load ir-*-decoder modules, but it does not wait or cancel this work on module unloading. rc-core should use request_module_nowait() instead, because it anyway cannot load modules synchronously or cancel/wait pending work on unloading, because this leads to deadlock on modules_mutex between several "modprobe" processes.

2012-12-21[media] rc: Call rc_register_device before irq setupMatthijs Kooijman
This should fix a potential race condition, when the irq handler triggers while rc_register_device is still setting up the rdev->raw device. This crash has not been observed in practice, but there should be a very small window where it could occur. Since ir_raw_event_store_with_filter checks if rdev->raw is not NULL before using it, this bug is not triggered if the request_irq triggers a pending irq directly (since rdev->raw will still be NULL then). This commit was tested on nuvoton-cir only.

2012-12-21[media] rc: Set rdev before irq setupMatthijs Kooijman
This fixes a problem in fintek-cir and nuvoton-cir where the irq handler would trigger during module load before the rdev member was set, causing a NULL pointer crash. It seems this crash is very reproducible (just bombard the receiver with IR signals during module load), probably because when request_irq is called, any pending intterupt is handled immediately, before request_irq returns and rdev can be set. This same crash was supposed to be fixed by commit 9ef449c6b31bb6a8e6dedc24de475a3b8c79be20 ("[media] rc: Postpone ISR registration"), but the crash was still observed on the nuvoton-cir driver.

Before, labels were simply numbered. Now, the labels are named after the cleanup action they'll perform (first), based on how the winbond-cir driver does it. This makes the code a bit more clear and makes changes in the ordering of labels easier to review. This change is applied only to the rc drivers that do significant cleanup in their probe functions: ati-remote, ene-ir, fintek-cir, gpio-ir-recv, ite-cir, nuvoton-cir. This commit should not change any code, it just renames goto labels.
