[PATCH 3.16 024/328] staging: rts5208: fix missing error check on call to rtsx_write_register

From: Ben Hutchings
Date: Sun Dec 09 2018 - 17:27:21 EST

3.16.62-rc1 review patch. If anyone has any objections, please let me know.


From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

commit c5fae4f4fd28189b1062fb8ef7b21fec37cb8b17 upstream.

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.
