From 9d32f82e040a823a584446cd9a7066390bf911fa Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Thu, 16 Jun 2016 13:38:24 +0200 Subject: [PATCH] mic: remove unused function arg MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit When building with W=1, the __scif_rma_destroy_tcw function causes a harmless warning about an argument variable that is modified but not used: drivers/misc/mic/scif/scif_dma.c: In function ‘__scif_rma_destroy_tcw’: drivers/misc/mic/scif/scif_dma.c:118:27: error: parameter ‘ep’ set but not used [-Werror=unused-but-set-parameter] In this case, we can just remove the argument, since all callers are in the same file.
