[Intel-gfx] [PATCH 1/4] drm/i915/guc: Update name and prototype of GuC submission related functions

Sagar Arun Kamble sagar.a.kamble at intel.com
Mon Nov 13 08:48:11 UTC 2017


i915 GuC submission is hardware interface and GuC APIs that are not user
facing should be named intel_guc* hence we change GuC submission related
functions name prefix to intel_guc. Also changed the parameter to these
functions to intel_guc struct.
