Folks,
in the discussion about preempt count consistency across kernel configurations:
https://lore.kernel.org/r/20200914204209.256266093@linutronix.de/
it was concluded that the usage of in_interrupt() and related context checks should be removed from non-core code.
In the long run, usage of 'preemptible, in_*irq etc.' should be banned from driver code completely.
This series targets the video subsystem.
