Subject: drm/amd/display: Use SIGNAL_TYPE_NONE in disable_output unless eDP
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=4338ffa8df23d6665f53dd38da2e415940e3bf13;p=linux.git

drm/amd/display: Use SIGNAL_TYPE_NONE in disable_output unless eDP

[WHY]
Currently made a change where disable_output is called using signal_type.
Using actual signal_type when calilng disable_output in power_down_encoders
would make DP to HDMI dongle not light up on boot. As it would have signal_type
SIGNAL_TYPE_DISPLAY_PORT.

[HOW]
Set signal_type to SIGNAL_TYPE_NONE unless it is eDP.
