From b9c8f86f50ac4555588fa85cec0c7f19b4dcdbdd Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Thu, 7 Mar 2019 11:11:30 +0100 Subject: [PATCH] ASoC: davinci-mcasp: Fix clang warning without CONFIG_PM [ Upstream commit 8ca5104715cfd14254ea5aecc390ae583b707607 ] Building with clang shows a variable that is only used by the suspend/resume functions but defined outside of their #ifdef block: sound/soc/ti/davinci-mcasp.c:48:12: error: variable 'context_regs' is not needed and will not be emitted We commonly fix these by marking the PM functions as __maybe_unused, but here that would grow the davinci_mcasp structure, so instead add another #ifdef here.
