  [PATCH] net: usb: asix_devices: fix missing return code check on call to asix_write_medium_mode Colin King <colin.king@canonical.com> - 2017-02-28 14:20 +0100

#1589437 — [PATCH] net: usb: asix_devices: fix missing return code check on call to asix_write_medium_mode

From: Colin Ian King <colin.king@canonical.com>

The call to asix_write_medium_mode is not updating the return code ret
and yet ret is being checked for an error. Fix this by assigning ret to
the return code from the call asix_write_medium_mode.

Detected by CoverityScan, CID#1357148 ("Logically Dead Code")
