The DP standard leaves ambiguity to if sink synchronization will be set before auxiliary protocols such as HDCP are to begin. Update the dp_display HDCP worker to check sink sync only if explicitly instructed to via the new debugfs node 'hdcp_wait_sink_sync' Change-Id: I4f4d0b14096aa3dc498e47de557de14092d37a58 Signed-off-by: Christopher Braga <cbraga@codeaurora.org>
