Subject: Input: ili210x - switch to using devm_device_add_group()
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=576057bf75cb3e40ff81bb01f021d76b764fdc92;p=openwrt%2Fstaging%2Fblogic.git

Input: ili210x - switch to using devm_device_add_group()

By switching to devm_device_add_group() we can complete driver conversion
to using managed resources and get rid of ili210x_i2c_remove().
