drm/i915: Convert wait_for(I915_READ(reg)) to intel_wait_for_register()
By using the out-of-line intel_wait_for_register() not only do we can efficiency from using the hybrid wait_for() contained within, but we avoid code bloat from the numerous inlined loops, in total (all patches): text data bss dec hex filename 1078551 4557 416 1083524 108884 drivers/gpu/drm/i915/i915.ko 1070775 4557 416 1075748 106a24 drivers/gpu/drm/i915/i915.ko Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Reviewed-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1467297225-21379-35-git-send-email-chris@chris-wilson.co.uk
