From 7d3beab16dd9eee86bb1a4dd05b51159fc7772f0 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Sat, 11 Apr 2015 00:27:58 +0200 Subject: dmaengine: shdmac: avoid unused variable warnings This driver uses '#ifdef CONFIG_ARCH_SHMOBILE' and '#ifdef CONFIG_ARM' interchangeably in its sh_dmae_probe function, which causes a build warning when building for ARM without also enabling shmobile: dma/sh/shdmac.c: In function sh_dmae_probe: dma/sh/shdmac.c:696:6: warning: unused variable errirq [-Wunused-variable] dma/sh/shdmac.c:695:16: warning: unused variable irqflags [-Wunused-variable] dma/sh/shdmac.c: At top level: dma/sh/shdmac.c:447:20: warning: sh_dmae_err defined but not used [-Wunused-function] This changes all the #ifdef to test for CONFIG_ARCH_SHMOBILE to avoid that warning. An earlier patch from Laurent had fixed the warning for non-ARM case, but it still remained present in ARM randconfig builds.
