From 414c52b7899aa9097c2fa8444654a866e1df4a0c Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Fri, 25 May 2018 23:08:30 +0200 Subject: pwm: stm32: Fix build warning with CONFIG_DMA_ENGINE disabled Without dmaengine support, we get a harmless warning about an unused function: drivers/pwm/pwm-stm32.c:166:12: error: 'stm32_pwm_capture' defined but not used [-Werror=unused-function] Changing the #ifdef to an IS_ENABLED() check shuts up that warning and is slightly nicer to read.
