Subject: [PATCH] remoteproc: imx_dsp_rproc: mark PM functions as __maybe_unused
Date: Thu, 14 Oct 2021 09:52:24 +0200 [thread overview]
Message-ID: <20211014075239.3714694-1-arnd@kernel.org> (raw)
From: Arnd Bergmann <arnd@arndb.de>
When CONFIG_PM_SLEEP is disabled, we get a harmless warning:
drivers/remoteproc/imx_dsp_rproc.c:1145:12: error: 'imx_dsp_resume' defined but not used [-Werror=unused-function]
1145 | static int imx_dsp_resume(struct device *dev)
| ^~~~~~~~~~~~~~
drivers/remoteproc/imx_dsp_rproc.c:1110:12: error: 'imx_dsp_suspend' defined but not used [-Werror=unused-function]
1110 | static int imx_dsp_suspend(struct device *dev)
| ^~~~~~~~~~~~~~~
Mark these as __maybe_unused to get a clean build.
Fixes: ec0e5549f358 ("remoteproc: imx_dsp_rproc: Add remoteproc driver for DSP on i.MX")
