Subject: [PATCH 2/7] led: pca955x: fix probing from device tree
Date: Mon, 28 Sep 2020 17:42:42 +0200	[thread overview]
Message-ID: <20200928154247.15619-2-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20200928154247.15619-1-a.fatoum@pengutronix.de>

dev->id_entry is not populated for devices probed from the device
tree. It was used unconditionally however. Use device_get_match_data
instead to support device tree probing.
