Subject: [PATCH] scsi: qla2xxx: fix return of uninitialized value in rval
Date:   Thu,  8 Oct 2020 19:32:39 +0100

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

A previous change removed the initialization of rval and there is
now an error where an uninitialized rval is being returned on an
error return path. Fix this by returning -ENODEV.

Addresses-Coverity: ("Uninitialized scalar variable")
Fixes: b994718760fa ("scsi: qla2xxx: Use constant when it is known")
