Hi Mauro,

I am copying this address for visibility.

  [PATCH v2] media: rc: fix use-after-free of rc_map.name on register
  error path

The remaining issue is a uevent racing with keymap cleanup while
registered is still true. The proposed approach is to clear registered
before freeing the keymap.

The follow-up linked below describes the remaining issue and the changes
needed for the current tree. I'd appreciate your feedback on the
proposed approach.
