Was not the decision that we only gate the MODULE_FIRMWARE line until the firmware is in linux-firmware.git? So it should be no harm to support loading firmwares that are available from drm-firmware.git as long as we don't add the MODULE_FIRMWARE which would trigger false positives for distro packagers.
