4.18-stable review patch. If anyone has any objections, please let me know.
------------------
From: Colin Ian King <colin.king@canonical.com>
[ Upstream commit c5fae4f4fd28189b1062fb8ef7b21fec37cb8b17 ]
Currently the check on error return from the call to rtsx_write_register is checking the error status from the previous call. Fix this by adding in the missing assignment of retval.
