Subject: [PATCH 1/1] leds-as3645a: Drop fwnode reference on ignored node
Date: Wed,  4 Dec 2019 09:56:42 +0200
Message-ID: <20191204075642.22070-1-sakari.ailus@linux.intel.com> (raw)

If a node is ignored, do not get a reference to it. Fix the bug by moving
fwnode_handle_get() where a reference to an fwnode is saved for clarity.
