Subject: [PATCH 09/13] platform: surface: Simplify with of_machine_get_match_data()
Date: Thu, 06 Nov 2025 20:07:16 +0100	[thread overview]
Message-ID: <20251106-b4-of-match-matchine-data-v1-9-d780ea1780c2@linaro.org> (raw)
In-Reply-To: <20251106-b4-of-match-matchine-data-v1-0-d780ea1780c2@linaro.org>

Replace open-coded getting root OF node, matching against it and getting
the match data with new of_machine_get_match_data() helper.

Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>

Depends on the first OF patch.
