[Joonas Lahtinen <jlahtine@jlahtine-mobl.ger.corp.intel.com>]

Hi Dave & Daniel,

Exactly same content as previous PR:

https://lists.freedesktop.org/archives/intel-gfx/2020-September/247626.html

Just rebased adding the missing S-o-b:s and updated "Fixes:" tags accordingly
as requested.

Regards, Joonas
