From: Alexandre Belloni <alexandre.bell...@free-electrons.com> When CONFIG_PM is defined but not CONFIG_PM_SLEEP (this happens when CONFIG_SUSPEND is not defined), there is the following warning:
drivers/spi/spi-atmel.c:1723:12: warning: ‘atmel_spi_suspend’ defined but not used [-Wunused-function] drivers/spi/spi-atmel.c:1741:12: warning: ‘atmel_spi_resume’ defined but not used [-Wunused-function] Enclose both atmel_spi_suspend and atmel_spi_resume in #ifdef CONFIG_PM_SLEEP/#endif to solve that.
