If anyone has any objections, please let me know. ------------------ From: Colin Ian King [ 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.
