Subject: [PATCH 02/10] media: renesas-ceu: Use of_device_get_match_data()
Date: Fri,  4 Oct 2019 14:43:26 -0700	[thread overview]
Message-ID: <20191004214334.149976-3-swboyd@chromium.org> (raw)
In-Reply-To: <20191004214334.149976-1-swboyd@chromium.org>

This driver can use the replacement API instead of calling
of_match_device() and then dereferencing the pointer that is returned.
This nicely avoids referencing the match table when it is undefined with
configurations where CONFIG_OF=n.
