We keep a cached version of the edid in radeon_connector which we use for determining connectedness and when to enable certain features like hdmi audio, etc. When the user uses the firmware interface to override the driver with some other edid the driver's copy is never updated. The fetch function will check if there is a user supplied edid and update the driver's copy if there is. bug: https://bugs.freedesktop.org/show_bug.cgi?id=80691 Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
