A simple state machine was added to saa7134_ts. It has three states: SAA7134_TS_STOPPED SAA7134_TS_BUFF_DONE SAA7134_TS_STARTED When buffer_setup is run we start the TS initialization: set SAA7134_TS_STOPPED. When all buffers are prepared we write data into DMA register and set SAA7134_TS_BUFF_DONE. When the first buffer is active start TS and set SAA7134_TS_STARTED. When ts_release is called stop TS and set SAA7134_TS_STOPPED. Signed-off-by: Beholder Intl. Ltd.

The driver_data field of the device structure was zeroed, thus losing this information. Many drivers set this up before calling video_device_register, so we have to ensure that it isn't lost. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

Cleanup v4l2-dev.[ch], add/improve comments and add a new helper function: video_drvdata() that can get the private driver data from a file struct. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

Now that all drivers set the release callback in the video_device struct we can put in a BUG_ON in video_register_device to ensure that the callback is always there. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

All drivers that call video_device_register where checked to see if they set the release callback of struct video_device. Where that callback was missing it was added. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

Add a second release function: video_device_release_empty It can be used by drivers that have statically allocated video_device structs. Its use usually, but not always, indicates laziness on the part of the driver programmer. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

cx18: Have CX23418 release buffers at end of capture. The CX23418 reuses task handles so we need to have it release the buffers associated with a task handle at the end of a capture. If we don't, buffer ids used for one type of stream in the driver (MPEG, TS, PCM), could be used for another type of stream by the CX23418, if a previously used handle is assigned to a different type of stream. The driver would drop valid buffers when this happened. Signed-off-by: Andy Walls <awalls@radix.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

cx18: Fix cx18_find_handle() and add error checking. cx18_find_handle() did not find a good task handle and would use the invalid task handle under common conditions. Added a define for the invalid task handle and added error checking as well. Signed-off-by: Andy Walls <awalls@radix.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

When a suspended device has been reset instead of being resumed, USB core calls the reset_resume method if available instead of unbinding and rebinding the device. This patch implements reset_resume by reusing the current resume implementation and simplifies the resume method by skipping the controls restore stage. Resuming from autosuspend should be faster.

The kernel.h macro DIV_ROUND_UP performs the computation (((n) + (d) - 1) / (d)) but is perhaps more readable.

This driver sure needs some rework. For now, let's try to clean it up a bit before start reimplementing anything. checkpatch.pl still not happy with this driver after this patch, but the most annoying errors are gone, comments now use C-style only, labels are well placed and some other minor fixes. Some more clean up patches will come as I work on this driver. Please review it carefully.
