Subject: [PATCH net-next 08/10] s390/qeth: cleanup OAT code
Date: Tue, 14 Jul 2020 16:23:03 +0200	[thread overview]
Message-ID: <20200714142305.29297-9-jwi@linux.ibm.com> (raw)
In-Reply-To: <20200714142305.29297-1-jwi@linux.ibm.com>

While initially just trying to fix up the indentation, condense a few
lines and get rid of a goto label.
