Subject: [PATCH] main/postmarketos-base-downstream: add disable-udev-v4l
 subpackage (MR 4768)

Which replaces /lib/udev/rules.d/60-persistent-v4l.rules (from the
eudev package) with a symlink to /dev/null.  Around 20 devices need
this to fix a kernel panic with downstream kernel when starting udev.
Issue happens due to that camera firmware is missing and/or not loaded
properly.
