Subject: [PATCH] iio: imx8qxp-adc: mark PM functions as __maybe_unused
Date: Wed, 13 Oct 2021 16:43:26 +0200 [thread overview]
Message-ID: <20211013144338.2261316-1-arnd@kernel.org> (raw)
From: Arnd Bergmann <arnd@arndb.de>
Without CONFIG_PM_SLEEP, the runtime suspend/resume functions
are unused, producing a warning:
drivers/iio/adc/imx8qxp-adc.c:433:12: error: 'imx8qxp_adc_runtime_resume' defined but not used [-Werror=unused-function]
433 | static int imx8qxp_adc_runtime_resume(struct device *dev)
| ^~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/iio/adc/imx8qxp-adc.c:419:12: error: 'imx8qxp_adc_runtime_suspend' defined but not used [-Werror=unused-function]
419 | static int imx8qxp_adc_runtime_suspend(struct device *dev)
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~
Mark them as __maybe_unused to shut up the compiler.
Fixes: 7bce634d02e6 ("iio: imx8qxp-adc: Add driver support for NXP IMX8QXP ADC")
