Subject: [PATCH] serial: st-asc: Potential error pointer dereference
Date: Mon, 17 Jul 2017 11:12:38 +0300 [thread overview]
Message-ID: <20170717081238.bjjp5vvzq56yv2q3@mwanda> (raw)
It looks like we intended to return an error code here, because we
dereference "ascport->pinctrl" on the next lines.
Fixes: 6929cb00a501 ("serial: st-asc: Read in all Pinctrl states")
