6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Roman Li <Roman.Li@xxxxxxx>
[ Upstream commit 60612f75992d96955fb7154468c58d5d168cf1ab ]
[Why]
Idle worker thread waits HPD_DETECTION_TIME for HPD processing complete.
Some displays require longer time for that.
[How]
Increase HPD_DETECTION_TIME to 100ms.
