Subject: mfd: act8945a: Use devm_mfd_add_devices() for mfd_device registration
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=f9932c6e66c17ca3d84a7c6424c844bea8003ffb;p=deliverable%2Flinux.git

mfd: act8945a: Use devm_mfd_add_devices() for mfd_device registration

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.
