#     Merge tag 'rpmsg-v5.17-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux
#     
#     Pull rpmsg fixes from Bjorn Andersson:
#      "The cdev cleanup in the rpmsg_char driver was not performed properly,
#       resulting in unpredicable behaviour when the parent remote processor
#       is stopped with any of the cdevs open by a client.
#     
#       Two patches transitions the implementation to use cdev_device_add()
#       and cdev_del_device(), to capture the relationship between the two
#       objects, and relocates the incorrectly placed cdev_del()"
#
