Subject[PATCH] HID: sony: remove redundant check for -ve err
Message-ID<tpH5T-3my-5@gated-at.bofh.it>
From: Colin Ian King <colin.king@canonical.com>

err is being checked for failure each time it is being updated
so this err check is totally redundant and can be removed

Detected with CoverityScan, CID#1420665 ("Logically dead code")
