From: Arnd Bergmann Date: Thu, 16 Jun 2016 11:38:24 +0000 (+0200) Subject: mic: remove unused function arg X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9d32f82e040a823a584446cd9a7066390bf911fa;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git mic: remove unused function arg 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.
