Subject: drm/amd/display: refine the EDID override
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=575d0df6dae46f1b5d26a35ce0ccbc5aafd40e1d;p=linux.git

drm/amd/display: refine the EDID override

[Why]
We already get the SBIOS EDID via ACPI on KMD,
but after that, we just use the monitor EDID to set it HDR caps

[How]
Make the SBIOS EDID override to read_edid()
That can change the read EDID caps from the right EDID
