Subject: [PATCH net-next 1/9] s390/qeth: don't call INIT_LIST_HEAD() on iob's list entry
Date: Tue, 17 Nov 2020 17:15:12 +0100	[thread overview]
Message-ID: <20201117161520.1089-2-jwi@linux.ibm.com> (raw)
In-Reply-To: <20201117161520.1089-1-jwi@linux.ibm.com>

INIT_LIST_HEAD() only needs to be called on actual list heads.
While at it clarify the naming of the field.
