Subject: drm/i915/gt: Use intel_gt as the primary object for handling resets
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=cb823ed9915b0d4064f3f51e936fbe13c089948a;p=openwrt%2Fstaging%2Fblogic.git

drm/i915/gt: Use intel_gt as the primary object for handling resets

Having taken the first step in encapsulating the functionality by moving
the related files under gt/, the next step is to start encapsulating by
passing around the relevant structs rather than the global
drm_i915_private. In this step, we pass intel_gt to intel_reset.c
