From abfa251afe27ee7820c3a082fe573ec5bedb3488 Mon Sep 17 00:00:00 2001 From: Anup Patel Date: Tue, 22 Aug 2017 15:26:55 +0530 Subject: [PATCH] dmaengine: bcm-sba-raid: Remove reqs_free_count from sba_device The reqs_free_count member of sba_device is not used anywhere hence no point in tracking number of free sba_request.
