2010-05-19V4L/DVB: ir-core: remove ir-functions usage from cx231xxDavid Härdeman
Convert drivers/media/video/cx231xx/cx231xx-input.c to not rely on ir-functions.c.

2010-05-19V4L/DVB: ir-core: remove IR_TYPE_PDDavid Härdeman
Pulse-distance is not a protocol, it is a line coding (used by some protocols, like NEC). Looking at the uses of IR_TYPE_PD, the real protocol seems to be NEC in all cases (drivers/media/video/cx88/cx88-input.c is the only user). So, remove IR_TYPE_PD while it is still easy to do so.

2010-05-19V4L/DVB: IR/imon: convert to ir-core protocol change handlingJarod Wilson
Drop the imon driver's internal protocol definitions in favor of using those provided by ir-core. Should make ir-keytable Just Work for switching protocol on the fly on the imon devices that support both the native imon remotes and mce remotes. The imon-no-pad-stabilize pseudo-protocol was dropped as a protocol, and converted to a separate modprobe option (which it probably should have been in the first place). On the TODO list is to convert this to an as yet unwritten protocol-specific options framework. While the mce remotes obviously map to IR_TYPE_RC6, I've yet to look at what the actual ir signals from the native imon remotes are, so for the moment, imon native ir is mapped to IR_TYPE_OTHER. Nailing it down more accurately is also on the TODO list. Signed-off-by: Jarod Wilson <jarod@redhat.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2010-05-19V4L/DVB: Fix color format with tm6010Mauro Carvalho Chehab
The values for the fourcc format were correct, but applied to the wrong register. With this change, video is now barely working again with tm6000. While here, let's remove, for now, the memset. This way, people can have some image when testing this device. Yet to be fixed: parts of the image frame are missed. As we don't clean the buffers anymore, this is "recovered" by repeating the values from a previous frame. The quality is bad, since the image pixels will contain data from some previous frames, generating weird delay artifacts. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2010-05-19V4L/DVB: tm6000: Fix a panic if buffer become NULLMauro Carvalho Chehab
Changing a video standard takes a long time to happen on tm6000, since it needs to load another firmware, and the i2c implementation on this device is really slow. When the driver tries to change the video standard, a kernel panic is produced: BUG: unable to handle kernel NULL pointer dereference at 0000000000000008 IP: [<ffffffffa0c7b48a>] tm6000_irq_callback+0x57f/0xac2 [tm6000] ... Kernel panic - not syncing: Fatal exception in interrupt By inspecting it with gdb: (gdb) list *tm6000_irq_callback+0x57f 0x348a is in tm6000_irq_callback (drivers/staging/tm6000/tm6000-video.c:202). 197 /* FIXME: move to tm6000-isoc */ 198 static int last_line = -2, start_line = -2, last_field = -2; 199 200 /* FIXME: this is the hardcoded window size 201 */ 202 unsigned int linewidth = (*buf)->vb.width << 1; 203 204 if (!dev->isoc_ctl.cmd) { 205 c = (header >> 24) & 0xff; 206 Clearly, it was the trial to access *buf, at line 202 that caused the Panic. As ioctl is serialized, While S_STD is handled,QBUF/DQBUF won't be called. So, the driver will run out of the buffers, and *buf will become NULL. As, on tm6000, the same URB can contain more than one video buffer, it is likely to hit a condition where no new buffer is available whily copying the streams. The fix is to leave the URB copy loop, if there's no more buffers are available. The same bug could also be produced by an application that is not fast enough to request new video buffers. The same bug were reported by Bee Hock Goh <beehock@gmail.com>. Thanks-to: Bee Hock Goh <beehock@gmail.com> for reporting the bug Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
