I prefer that you would put recipient specifications also into the message field “To”
(besides “Cc”).

> To fix this, this patch holds and locks the l2cap channel.

Please choose a corresponding imperative wording.

You would probably like to improve your patch approach further
so that provided data will be kept consistent.
