Subject: [PATCH] firmware: arm_scpi: Use device_get_match_data()
Date: Fri, 6 Oct 2023 17:46:50 -0500 [thread overview]
Message-ID: <20231006224650.445424-1-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.
