Subject: [PATCH] net: phy: mdio-bcm-unimac: remove redundant !timeout check
Date: Wed, 27 Mar 2019 16:15:20 +0000 [thread overview]
Message-ID: <20190327161520.23064-1-colin.king@canonical.com> (raw)
From: Colin Ian King <colin.king@canonical.com>
The check for zero timeout is always true at the end of the proceeding
while loop; the only other exit path in the loop is if the unimac MDIO
is not busy. Remove the redundant zero timeout check and always
return -ETIMEDOUT on this timeout return path.
