2010-02-26V4L/DVB: radio: add support for SAA7706H Car Radio DSPRichard Röjfors
Initial support for the SAA7706H Car Radio DSP. It is a I2C device and currently the mute control is supported. When the device is unmuted it is brought out of reset and initiated using the proposed intialisation sequence. When muted the DSP is brought into reset state.

2010-02-26V4L/DVB: cx18: Add missing serialization locks to cx18-dvbAndy Walls
Operations that manipulates the state of the encoder or global instance flags and variables should be serialized. This adds some serialization locks that have been missing from cx18-dvb. Since the DVB part of the CX23418 doesn't affect the encoder, no one would likely have ever noticed a race in changing card instance variables.

2010-02-26V4L/DVB: cx18: Fix memory leak in cx18-alsa starting of PCM capturesAndy Walls
The cx18_open_id is normally dynamically allocated and stored in the filp->private_data for v4l2 file operations. The cx18-alsa routines should not dynamically allocate a cx18_open_id because they never store it anywhere and never free it. This change fixes that and plugs a memory leak.

2010-02-26V4L/DVB: Fix VIDIOC_QBUF compat ioctl32Arnaud Patard
When using VIDIOC_QBUF with memory type set to V4L2_MEMORY_MMAP, the v4l2_buffer buffer gets unmodified on drivers like uvc (well, only bytesused field is modified). Then some apps like gstreamer are reusing the same buffer later to call munmap (eg passing the buffer "length" field as 2nd parameter of munmap). It's working fine on full 32bits but on 32bits systems with 64bit kernel, the get_v4l2_buffer32() doesn't copy length/m.offset values and then copy garbage to userspace in put_v4l2_buffer32(). This has for consequence things like that in the libv4l2 logs: libv4l2: v4l2 unknown munmap 0x2e2b0000, -2145144908 libv4l2: v4l2 unknown munmap 0x2e530000, -2145144908 The buffer are not unmap'ed and then if the application close and open again the device, it won't work and logs will show something like: libv4l2: error setting pixformat: Device or resource busy The easy solution is to read length and m.offset in get_v4l2_buffer32().

2010-02-26V4L/DVB: firedtv: remove check for interrupting signalStefan Richter
FCP transactions as well as CMP transactions were serialized with mutex_lock_interruptible. It is extremely unlikly though that a signal will arrive while a concurrent process holds the mutex. And even if one does, the duration of a transaction is reasonably short (1.2 seconds if all retries time out, usually much shorter). Hence simplify the code to plain mutex_lock.

2010-02-26V4L/DVB: firedtv: do not DMA-map stack addressesStefan Richter
This is a portability fix and reduces stack usage. The DMA mapping API cannot map on-stack addresses, as explained in Documentation/DMA-mapping.txt. Convert the two cases of on-stack packet payload buffers in firedtv (payload of write requests in avc_write and of lock requests in cmp_lock) to slab-allocated memory. We use the 512 bytes sized FCP frame buffer in struct firedtv for this purpose. Previously it held only incoming FCP responses, now it holds pending FCP requests and is then overwriten by an FCP response from the tuner subunit. Ditto for CMP lock requests and responses. Accesses to the payload buffer are serialized by fdtv->avc_mutex. As a welcome side effect, stack usage of the AV/C transaction functions is reduced by 512 bytes. Alas, avc_register_remote_control() is a special case: It previously did not wait for a response. To fit better in with the other FCP transactions, let it wait for an interim response.
