* V4L/DVB (10135): v4l2: introduce v4l2_file_operations.Hans Verkuil2009-01-021-7/+5
| | | | | | | | | | | | | | | | Introduce a struct v4l2_file_operations for v4l2 drivers. Remove the unnecessary inode argument. Move compat32 handling (and llseek) into the v4l2-dev core: this is now handled in the v4l2 core and no longer in the drivers themselves. Note that this changeset reverts an earlier patch that changed the return type of__video_ioctl2 from int to long. This change will be reinstated later in a much improved version.

* V4L/DVB (8906): v4l-dvb: fix assorted sparse warningsHans Verkuil2008-10-121-1/+1
| | | | | | | | | | Fix sparse warnings. None are serious, but cutting down on these helps find future serious sparse warnings/errors. Redid the av7710.c patch based on a suggestion by Oliver Endriss. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

| | | | | | | | | | Remove the priv field and let video_get/set_drvdata use dev_get_drvdata and dev_set_drvdata instead. Convert all drivers that still used priv directly. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

| | | | | | | | | | Fix for reloading firmware when removing and reloading driver Handshaking for firmware loading and changing modes. Removes the restriction of one user per channel at a time.

* V4L/DVB (8613): v4l: move BKL down to the driver level.Hans Verkuil2008-10-121-0/+6
| | | | | | | | | | | The BKL is now moved from the video_open function in v4l2-dev.c to the various drivers. It seems about a third of the drivers already has a lock of some sort protecting the open(), another third uses video_exclusive_open (yuck!) and the last third required adding the BKL in their open function.

| | | | | | | | | The type and type2 fields were unused and so could be removed. Instead add a vfl_type field that contains the type of the video device. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

| | | | | | | | | | | This patch fixes timer issues in driver disconnect. It also removes the restriction of one user per channel at a time. Thanks to Oliver Neukum and Mauro Chehab for finding these issues. Locking of video stream partly based on saa7134 driver.

* V4L/DVB (8482): videodev: move all ioctl callbacks to a new v4l2_ioctl_ops ↵Hans Verkuil2008-07-261-6/+10
| | | | | | | | | | | | | struct All ioctl callbacks are now stored in a new v4l2_ioctl_ops struct. Drivers fill in a const struct v4l2_ioctl_ops and video_device just contains a const pointer to it. This ensures a clean separation between the const ops struct and the non-const video_device struct.
