[PATCH V2 10/20] mfd: mt6397: Use devm_mfd_add_devices() for mfd_device registration

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

 



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.
