Subject: [PATCH v2 05/17] staging: qlge: Remove bq_desc.maplen
Date: Fri, 27 Sep 2019 19:11:59 +0900 [thread overview]
Message-ID: <20190927101210.23856-6-bpoirier@suse.com> (raw)
In-Reply-To: <20190927101210.23856-1-bpoirier@suse.com>
The size of the mapping is known statically in all cases, there's no need
to save it at runtime. Remove this member.
