Russell King 0fc6f44d96 drm/i2c: tda998x: re-implement "Fix EDID read timeout on HDMI connect" ... Commit 6833d26ef8 ("drm: tda998x: Fix EDID read timeout on HDMI connect") used a weak scheme to try and delay reading EDID on a HDMI connect event. It is weak because delaying the notification of a hotplug event does not stop userspace from trying to read the EDID within the 100ms delay. The solution provided here solves this issue: * When a HDMI connection event is detected, mark a blocking flag for EDID reads, and start a timer for the delay. * If an EDID read is attempted, and the blocking flag is set, wait for the blocking flag to clear. * When the timer expires, clear the blocking flag and wake any thread waiting for the EDID read.
