* [media] lirc_zilog: Restore checks for existence of the IR_tx objectAndy Walls2011-03-22
| | | | | | | | | | | | | This reverts commit 8090232a237ab62e22307fc060097da1a283dd66 and adds an additional check for ir->tx == NULL. The user may need us to handle an RX only unit. Apparently there are TV capture units in existence with Rx only wiring and/or RX only firmware for the on-board Zilog Z8 IR unit.

* [media] tm6000: fix s-video inputDmitri Belimov2011-03-22
| | | | | | | | | | | | | | | | | | | | | Add compatibility for composite and s-video inputs. Some TV cards hasn't it. Fix S-Video input, the s-video cable has only video signals no audio. Call the function of audio configure kill chroma in signal. only b/w video. Known bugs: - after s-video the audio for radio didn't work, TV crashed hardly - after composite TV crashed hardly too. P.S. After this patch I'll want to rework the procedure of configure video. Now it has a lot of junk and dubles. With my best regards, Dmitry. Signed-off-by: Beholder Intl. Ltd.

* [media] rc: New rc-based ite-cir driver for several ITE CIRsJuan J. Garcia de Soria2011-03-22
| | | | | | | | | | | | | | | | | | | | | | | | This is a second version of an rc-core based driver for the ITE Tech IT8712F CIR and now for a pair of other variants of the IT8512 CIR too. This driver should replace the lirc_it87 and lirc_ite8709 currently living in the LIRC staging directory. The driver should support the ITE8704, ITE8713, ITE8708 and ITE8709 (this last one yet untested) PNP ID's. The code doesn'te reuse code from the pre-existing LIRC drivers, but has been written from scratch using the nuvoton.cir driver as a skeleton. This new driver shouldn't exhibit timing problems when running under load (or with interrupts disabled for relatively long times). It works OOTB with the RC6 MCE remote bundled with the ASUS EEEBox. TX support is implemented, but I'm unable to test it since my hardware lacks TX capability. Signed-off-by: Juan J.

* [media] saa7134: Fix strange kconfig dependency on RC_CORESteven Rostedt2011-03-22
| | | | | | | | | | | | | | | | | | | | | | As the code in saa7134-input is not a module, but the config for it is set as a boolean instead of a tristate, this causes a strange dependency on RC_CORE. VIDEO_SAA7134_RC (which determines if saa7134-input.o is built) depends on RC_CORE and VIDEO_SAA7134. If VIDEO_SAA7134 is compiled as 'y' but RC_CORE is compiled as 'm' VIDEO_SAA7134_RC can still be set to 'y' which causes undefined symbols that it needs from RC_CORE. The simplest solution is to not allow VIDEO_SAA7134_RC be enabled if RC_CORE compiled as a module (m) and VIDEO_SA7134 is compiled into the kernel (y).

* [media] v4l2-device: add kref and a release functionHans Verkuil2011-03-22
| | | | | | | | | | | | | | | | | | The video_device struct has proper ref counting and its release function will be called when the last user releases it. But no such support was available for struct v4l2_device. This made it hard to determine when a USB driver can release the device if it has multiple device nodes. With one device node it is easy of course, since when the device node is released, the whole device can be released. This patch adds refcounting to v4l2_device. When registering device nodes the v4l2_device refcount will be increased, when releasing device nodes it will be decreased. The (optional) release function will be called when the last device node was released. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

| | | | | | | | | | | | | On my AverMedia AverTV Studio 507, key up events are no longer sent after a suspend-to-disk/resume cycle, resulting in "stuck" keys. Apparently, for key up events to be generated, a certain GPIO pin must be set. Currently it's set in saa7134_input_init1(), but that function is not called on device resume. I suggest that code be moved to __saa7134_ir_start(), which is called both on init and resume.

It makes a lot of sense. Changing it is not a problem :) How about the updated patch below? If the memory allocation to 'state' succeeds but we jump to the 'error' label before 'state' is assigned to fe->tuner_priv, then the call to 'zl10036_release(fe)' at the 'error:' label will not free 'state', but only what was previously assigned to 'tuner_priv', thus leaking the memory allocated to 'state'. This patch fixes the leak and also does not jump to 'error:' before mem has been allocated but instead just returns. Also some small style cleanups.
