Subject: [PATCH] drm/vc4: Only add gamma properties once.
|
|
|
|
|
|
|
|
|
|
Two calls were made to drm_crtc_enable_color_mgmt to add gamma
|
|
|
|
|
and CTM, however they were both set to add the gamma properties,
|
|
|
|
|
so they ended up added twice.
|
|
|
|
|
|
|
|
|
|
Fixes: 766cc6b1f7fc "drm/vc4: Add CTM support"
