Subject: [PATCH -next] misc: mic: scif: remove set but not used variables 'src_dma_addr, dst_dma_addr'
Date: Fri, 12 Oct 2018 03:25:56 +0000 [thread overview]
Message-ID: <1539314756-154517-1-git-send-email-yuehaibing@huawei.com> (raw)
Fixes gcc '-Wunused-but-set-variable' warning:
drivers/misc/mic/scif/scif_dma.c: In function 'scif_rma_list_dma_copy_wrapper':
drivers/misc/mic/scif/scif_dma.c:1558:27: warning:
variable 'dst_dma_addr' set but not used [-Wunused-but-set-variable]
drivers/misc/mic/scif/scif_dma.c:1558:13: warning:
variable 'src_dma_addr' set but not used [-Wunused-but-set-variable]
They never used since introduction in
commit 7cc31cd27752 ("misc: mic: SCIF DMA and CPU copy interface")
