Subject: drm/i915: Use drm_i915_private as the native pointer for intel_uncore.c
X-Git-Tag: MMI-PSA29.97-13-9~7427^2~45^2~95
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=dc97997a21fe1708fc93021baa4ba90db7a3b57f;p=GitHub%2FMotorolaMobilityLLC%2Fkernel-slsi.git

drm/i915: Use drm_i915_private as the native pointer for intel_uncore.c

Pass drm_i915_private to the uncore init/fini routines and their
subservients as it is their native type.
