[media] saa7146: replace current->state by set_current_state()

2015-03-03T14:15:42+00:00

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.

filling up the logs(one about every 5 seconds).

Other posts suggests that it is not actually an error on cards without a
CI interface. Here's a patch that turns it into a debug message, so it
does not clobber the logs.

[media] saa7146: Create a device name before it's used

2014-10-21T10:51:44+00:00

request_irq() uses it, tries to create a procfs file with an empty name
otherwise.

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

2014-07-04T19:14:59+00:00

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.
