6.6-stable review patch. If anyone has any objections, please let me know.

From: Chen Ni nichen@iscas.ac.cn
[ 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.
