[PATCH] drm/i915/hdcp: Add additional R0' wait

2020-05-19 Thread Sean Paul
From: Sean Paul We're seeing some R0' mismatches in the field, particularly with repeaters. I'm guessing the (already lenient) 300ms wait time isn't enough for some setups. So add an additional wait when R0' is mismatched. Signed-off-by: Sean Paul --- drivers/gpu/drm/i915/display/intel_hdcp.c
