[media] hdpvr: embed video_device

2015-04-03T02:36:54Z

[media] hdpvr: reduce memory footprint when debugging

2014-09-23T19:13:36Z

There is no need to use hex_dump_to_buffer() since we have a kernel helper to dump up to 64 bytes just via printk(). Signed-off-by: Andy Shevchenko Signed-off-by: Mauro Carvalho Chehab

[media] v4l: Support extending the v4l2_pix_format structure

2014-07-17T15:44:47Z

The v4l2_pix_format structure has no reserved field. It is embedded in the v4l2_framebuffer structure which has no reserved fields either, and in the v4l2_format structure which has reserved fields that were not previously required to be zeroed out by applications. To allow extending v4l2_pix_format, inline it in the v4l2_framebuffer structure, and use the priv field as a magic value to indicate that the application has set all v4l2_pix_format extended fields and zeroed all reserved fields following the v4l2_pix_format field in the v4l2_format structure. The availability of this API extension is reported to userspace through the new V4L2_CAP_EXT_PIX_FORMAT capability flag. Just checking that the priv field is still set to the magic value at [GS]_FMT return wouldn't be enough, as older kernels don't zero the priv field on return. To simplify the internal API towards drivers zero the extended fields and set the priv field to the magic value for applications not aware of the extensions.

[media] media: remove the setting of the flag V4L2_FL_USE_FH_PRIO

2014-07-04T19:14:59Z

Since all the drivers that use `struct v4l2_fh' use the core priority checking, the setting of the flag in the drivers can be removed. Signed-off-by: Ramakrishnan Muthukrishnan Reviewed-by: Hans Verkuil Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] hdpvr: fix two audio bugs

2014-07-04T18:13:02Z

When the audio encoding is changed the driver calls hdpvr_set_audio with the current opt->audio_input value. However, that should have been opt->audio_input + 1. So changing the audio encoding inadvertently changes the input as well. This bug has always been there. The second bug was introduced in kernel 3.10 and that broke the default_audio_input module option handling: the audio encoding was never switched to AC3 if default_audio_input was set to 2 (SPDIF input). In addition, since starting with 3.10 the audio encoding is always set at the start the first bug now always happens when the driver is loaded. In the past this bug would only surface if the user would change the audio encoding after the driver was loaded. Also fixes a small trivial typo (bufffer -> buffer).

[media] hdpvr: fix iteration over uninitialized lists in hdpvr_probe()

2013-09-03T12:24:20Z

free_buff_list and rec_buff_list are initialized in the middle of hdpvr_probe(), but if something bad happens before that, error handling code calls hdpvr_delete(), which contains iteration over the lists (via hdpvr_free_buffers()). The patch moves the lists initialization to the beginning and by the way fixes goto label in error handling of registering videodev. Found by Linux Driver Verification project (linuxtesting.org).
