[Intel-gfx] [PULL] drm-intel-fixes

[Joonas Lahtinen]

Hi Dave & Daniel,

Some rather important fixes that appeared after -rc6 and
missed v5.2. As a PR by request of Daniel.

These avoid one WARN and potential dirty pointer deref,
fix a regression on saturated media loads and add missing
Icelake W/As.

I've manually added Cc: stable to all of them. There's also one
patch that is dependency to the Icelake W/A code.

Regards, Joonas
