Subject: [PATCH] drm/edid: When reset, assume HDMI displays support RGB444
|
|
|
|
If an HDMI connector has no EDID and the mode is set via the
|
|
kernel command line, then drm_reset_display_info() is the only
|
|
thing that will have set up any of connector->display_info.
|
|
|
|
With commit 26ff1c38fc29 ("drm/connector: hdmi: Compute bpc
|
|
and format automatically"), it is now checked that
|
|
DRM_COLOR_FORMAT_RGB444 is supported. Whilst it doesn't fail
|
|
the request, it does log dev_warn for every commit, spamming
|
|
the log.
|
|
|
|
For HDMI connectors initialise the color_format field to say
|
|
it supports RGB444.
