From a0319f8b12c0fb9800da61f4cba9bd6fd80e37a4 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Thu, 15 Sep 2016 17:46:53 +0200 Subject: [PATCH] spi: bcm-qspi: fix suspend/resume #ifdef The two power management functions are define inside of an #ifdef but referenced unconditionally, which is obviously broken when CONFIG_PM_SLEEP is not set: drivers/spi/spi-bcm-qspi.c:1300:13: error: 'bcm_qspi_suspend' undeclared here (not in a function) drivers/spi/spi-bcm-qspi.c:1301:13: error: 'bcm_qspi_resume' undeclared here (not in a function) This replaces the #ifdef with a __maybe_unused annotation that lets the compiler figure out whether to drop the functions itself, and uses SIMPLE_DEV_PM_OPS() to refer to the functions. This will also fill the freeze/thaw/poweroff/restore callback pointers in addition to suspend/resume, but as far as I can tell, this is what we want.
