Description Göran Uddeborg 2019-08-11 11:58:26 UTC
When looking through the boot messages more closely than usual, I found the message

  aug 10 12:01:53 mimmi kernel: [drm] drm_kms_firmware.edid_firmware is deprecated, please use drm.edid_firmware instead.

When trying to do as I was told, it was confusing since I couldn't find I used "drm_kms_firmware" when grep:ing through my configurations.  It turns out I used the parameter drm_kms_helper.edid_firmware.  If I understand how the code in drivers/gpu/drm/drm_kms_helper_common.c correctly, that is indeed the parameter being warned about.  This might simply be a typo in the message, unless there is something I'm missing.
