Subject: [PATCH] watchdog: st_lpc: Use device_get_match_data()
Date: Mon, 9 Oct 2023 16:13:48 -0500 [thread overview]
Message-ID: <20231009211356.3242037-18-robh@kernel.org> (raw)
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.
