Message-Id: <20231006224446.443015-1-robh@kernel.org>
Date: Fri, 6 Oct 2023 17:44:46 -0500

linux-omap@...r.kernel.org
Subject: [PATCH] i2c: Use device_get_match_data()
Use preferred device_get_match_data() instead of of_match_device() to
get the driver match data. With this, adjust the includes to explicitly
include the correct headers.
