Subject: drm/i915/DMC/KBL: Load DMC on KBL using the no_stepping_info array
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1c00164d4cd1f513ea44a1b068490e52e7cbf04f;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

drm/i915/DMC/KBL: Load DMC on KBL using the no_stepping_info array

Currently, for display there is only one DMC image for KBL.
Remove the stepping_info table for KBL and use the no_stepping_info
array for loading the firmware.

v2: Removed the block of code as pointed out by Rodrigo to make the
loads as generic as possible.
