Subject: [PATCH] iio: accel: mma9551: Protect PM-only functions by #ifdef CONFIG_PM_SLEEP
Date: Wed, 18 Feb 2015 11:47:12 +0100 [thread overview]
Message-ID: <1424256432-20808-1-git-send-email-geert@linux-m68k.org> (raw)
If CONFIG_PM_SLEEP=n:
drivers/iio/common/ssp_sensors/ssp_dev.c:644: warning: ‘ssp_suspend’ defined but not used
drivers/iio/common/ssp_sensors/ssp_dev.c:669: warning: ‘ssp_resume’ defined but not used
Protect the unused functions by #ifdef CONFIG_PM_SLEEP to fix this.
Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org>
