[PATCH v5 next 6/7] iio: sca3000: stop interrupts via devm_add_action_or_reset()
Posted by Harshit Mogalapalli 4 days, 8 hours ago
Used devm_add_action_or_reset() for shutting down the interrupts.
Make sca3000_stop_all_interrupts() return void now that it always hooks
into devm cleanup.

No functional change intended.

v4->v5: Offloaded the move of the sca3000_stop_all_interrupts() above
probe in a earlier patch, thanks to Andy for the suggestion of making
this simple.
