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@xxxxxxxxxxxxxxxxxx> Reviewed-by: Tvrtko Ursulin <tvrtko.ursulin@xxxxxxxxx> --- drivers/gpu/drm/i915/intel_dsi.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) diff --git a/drivers/gpu/drm/i915/intel_dsi.c b/drivers/gpu/drm/i915/intel_dsi.c index a28dc1845455..448741d8653b 100644 --- a/drivers/gpu/drm/i915/intel_dsi.c +++ b/drivers/gpu/drm/i915/intel_dsi.c @@ -679,8 +679,9 @@ static void intel_dsi_clear_device_ready(struct intel_encoder *encoder) /* Wait till Clock lanes are in LP-00 state for MIPI Port A * only.
