[Intel-gfx] [PATCH v3 03/12] drm/i915/guc: Pass intel_guc struct parameter to GuC interrupts functions

Sagar Arun Kamble sagar.a.kamble at intel.com
Thu Jan 4 16:21:45 UTC 2018


GuC interrupts handling functions are GuC specific functions hence update
the parameter from dev_priv to intel_guc struct.

v2-v3: Rebase.
