Subject: [PATCH v7 1/5] leds: populate the device's of_node when possible
Date: Wed, 18 Sep 2019 16:57:26 +0200	[thread overview]
Message-ID: <20190918145730.22805-2-jjhiblot@ti.com> (raw)
In-Reply-To: <20190918145730.22805-1-jjhiblot@ti.com>

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).
