6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Chen Ni <nichen@xxxxxxxxxxx>
[ Upstream commit 0780c836673b25f5aad306630afcb1172d694cb4 ]
As platform_driver_register() and register_rpmsg_driver() can return
error numbers, it should be better to check the return value and deal
with the exception.
