Subject: [PATCH v7 1/5] leds: populate the device's of_node when possible
Date:   Wed, 18 Sep 2019 16:57:26 +0200

If initialization data is available and its fwnode is actually a of_node,
store this information in the led device's structure. This will allow the
device to use or provide OF-based API such (devm_xxx).
