[media] v4l2-core: drop g/s_priority ops

2015-03-02T20:09:43+00:00

The handling of VIDIOC_G/S_PRIORITY is now entirely done by the V4L2
core, so we can drop the g/s_priority ioctl ops.

We do have to make sure though that when S_PRIORITY is called we check
that the driver used struct v4l2_fh. This check can be removed once all
drivers are converted to that structure.

[media] v4l2 core: improve debug flag handling

2014-12-23T12:31:37+00:00

The old debug field is renamed to dev_debug to ensure that existing drivers
(including out-of-tree drivers) that try to use the old name will no longer
compile. A comment has also been added that makes it explicit that drivers
shouldn't use this field.

Additional bits have been added to the debug flag to be more fine-grained
when debugging, especially when dealing with streaming ioctls and read,
write and poll. You want to enable those explicitly to prevent flooding
the log when streaming unless you actually want to do that.
