Merge tag 'rpmsg-v6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux

Pull rpmsg updates from Bjorn Andersson:

 - rpmsg ctrl and char driver locking is ensure ordering in cases where
   the communication link is being torn down in parallel with calls to
   open(2) or poll(2)

 - The glink driver is refactored, to move rpm/smem-specifics out of the
   common logic and better suite further improvements, such as
   transports without a mailbox controller. The handling of remoteproc
   shutdown is improved, to fail clients immediately instead of having
   them to wait for timeouts. A driver_override memory leak is corrected
   and a few spelling improvements are introduced

 - glink_ssr is transitioned off strlcpy() and "gpr" is added as a valid
   child node of the glink-edge DT binding
