X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=e253fb0472e7a892176c7a65cef61a6aa75f8d2e;p=openwrt%2Fstaging%2Fblogic.git

mfd: stw481x: 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.
