[PATCH v2 06/51] iio:accel:mma7660: Switch from CONFIG_PM_SLEEP guards to pm_sleep_ptr()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Jonathan Cameron <Jonathan.Cameron@xxxxxxxxxx>

Letting the compiler remove these functions when the kernel is built
without CONFIG_PM_SLEEP support is simpler and less error prone than the
use of #ifdef based config guards.

Removing instances of this approach from IIO also stops them being
copied into new drivers.
