There have been other places where this was an issue before too (ext4,
mac80211, USB gadget, ...). Some have already been fixed.

Hmm. Yeah, I thought we had a patch for bluetooth too. I can't find it
now though.

Suffice it to say that similar patches are required for the other
instances of this kind of code elsewhere as well.

Thanks Marcel,
