[PATCH 4.5 097/200] drm/i915/skl: Fix DMC load on Skylake J0 and K0

From: Greg Kroah-Hartman
Date: Mon May 02 2016 - 21:07:43 EST


4.5-stable review patch. If anyone has any objections, please let me know.

------------------

From: Mat Martineau <mathew.j.martineau@xxxxxxxxxxxxxxx>

commit a41c8882592fb80458959b10e37632ce030b68ca upstream.

The driver does not load firmware for unknown steppings, so these new
steppings must be added to the list.
