Changes since v1:
- Update drivers to new set of macros
Raag Jadav (10):
PM: Introduce export macros for _SIMPLE_ variants of _PM_OPS()
PM: Update EXPORT_*_DEV_PM_OPS() to EXPORT_*_RUNTIME_PM_OPS()
iio: accel: fxls8962af: conve
Introduce a new set of export macros for _SIMPLE_ variants of _PM_OPS(),
which export dev_pm_ops symbol only in case CONFIG_PM_SLEEP=y and discard
it otherwise.
