Chris Wilson 2ca17b87e8 drm/i915: Add missing rpm wakelock to GGTT pread ... Joonas spotted a discrepancy between the pwrite and pread ioctls, in that pwrite takes the rpm wakelock around its GGTT access, The wakelock is required in order for the GTT to function. In disregard for the current convention, we take the rpm wakelock around the access itself rather than around the struct_mutex as the nesting is not strictly required and such ordering will one day be fixed by explicitly noting the barrier dependencies between the GGTT and rpm.
