Use helper functions to access current->state. Direct assignments are prone to races and therefore buggy. current->state = TASK_RUNNING can be replaced by __set_current_state() Thanks to Peter Zijlstra for the exact definition of the problem. Suggested-By:

Fix a few minor CodingStyle issues at the source code: - Use proper multi-line comments; - Align the log tables; - Remove the .type from dvb_frontend_ops, since this is not needed anymore (since the drivers conversion to DVBv5); - Remove emacs format macro. Signed-off-by: -

Ideally, we should be replacing this function by intlog10(). While we don't do that, let's at least constify the tables, in order to remove its code footfrint, and get rid of nelems. This also fixes a few 80-cols CodingStyle warnings. Signed-off-by: -

The logic there is too complex and it looks like an inifite loop. So, simplify the logic and implement it as a for loop.

Use pr_foo() where there's a direct replacement. For debug, use custom-made macros, for now, as there are 3 different debug levels. We should get rid of those some day, specially since several such macros can be just removed, as Kernel trace would provide about the same output.

While this is not a mandatory rule at the CodingStyle, we prefer hexadecimal values in lowercase. Currently, there's a mix of lowercase and uppercase ons at lgdt3306a. So, convert all to lowercase with this small script: perl -ne 'if (m,0x([\dA-F]+),) { $o=$1; $n=lc $1; s,0x($o),0x$n, } print $_' Signed-off-by: -

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. Signed-off-by:

Hans Verkuil authored
By using struct v4l2_fh both the prio handling and the linked list implementation in pvrusb2 can be removed since both are now done in the v4l2 core if you use struct v4l2_fh. Signed-off-by:

Hans Verkuil authored
To keep V4L2 drivers that did not yet convert to unlocked_ioctl happy, the v4l2 core had a .ioctl file operation that took a V4L2 lock. The last drivers are now converted to unlocked_ioctl, so all this old code can now be removed. Signed-off-by:

Hans Verkuil authored
Switch this driver over to the V4L2 core locking mechanism in preparation for switching to unlocked_ioctl. Suggested by Laurent Pinchart. This patch introduces a new mutex at the struct uvc_video level and drops the old mutex at the queue level. The new lock is now used for all ioctl locking and in the release file operation (the driver always has to take care of locking in file operations, the core only serializes ioctls). Note that the mmap and get_unmapped_area file operations no longer take a lock. Commit f035eb4e fixed a AB-BA deadlock by moving all the locking down into vb2, so the mmap and get_unmapped_area file operations should no longer do any locking before calling into vb2.
