[Intel-gfx] [PATCH 0/3] Fixes for runtime PM on planes APIs

[Paulo Zanoni]

From: Paulo Zanoni <paulo.r.zanoni at intel.com>

Hi

This series fixes some bugs that happen when we're runtime suspended and try to
use the planes APIs. I also wrote IGT test cases for the bugs, so we will be
able to detect future regressions.

The controversial part of these patches is that we had previously defined that
we wanted to get/put runtime PM in the highest level of the stack, wrapping as
much code as possible, but Daniel asked me to only get/put runtime PM around the
functions that pin the objects (still on the highest level, but only around the
pin functions). This series implements Daniel's suggestions.

Thanks,
Paulo
