Subject: [PATCH 01/19] usbnet: smsc95xx: Fix memory leak in smsc95xx_bind
Date: Thu, 3 Jan 2019 02:10:22 +0100 [thread overview]
Message-ID: <20190103011040.25974-2-marex@denx.de> (raw)
In-Reply-To: <20190103011040.25974-1-marex@denx.de>
In case reading of PHY register fails in smsc95xx_bind(), the private
data allocated earlier are not free()d. Free them before bailing out.
