Subject: [PATCH] power: reset: vexpress: Use device_get_match_data()
Date:   Mon,  9 Oct 2023 12:29:14 -0500
Message-ID: <20231009172923.2457844-19-robh@kernel.org>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

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.
