[PATCH 0/3] video: Remove in_interrupt() usage.

Folks,

in the discussion about preempt count consistency across kernel
configurations:

 https://lore.kernel.org/r/20200914204209.256266093@linutronix.de/ (local)

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. The omap patches are a repost
