Subject: [PATCH 0/3] video: Remove in_interrupt() usage.
Date: Mon,  8 Feb 2021 23:38:07 +0100	[thread overview]
Message-ID: <20210208223810.388502-1-bigeasy@linutronix.de> (raw)

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. The omap patches are a repost
of [0], the amba-clcd is new after I received no feedback on my analysis
[1].
