[PATCH V2 05/20] mfd: atmel-hlcdc: Use devm_mfd_add_devices() for mfd_device registration

From: Laxman Dewangan
Date: Thu Apr 07 2016 - 14:59:42 EST


Use devm_mfd_add_devices() for MFD devices registration and get
rid of .remove callback to remove MFD child-devices. This is done
by managed device framework.
