Subject: serial: st-asc: Potential error pointer dereference
From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>
commit 2b01bfaeb41e1563322448d9b392ac924cbf22ef upstream.
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")
