Subject: [PATCH v4 03/10] media: samsung: exynos4-is: drop simple-bus from compatibles
Date: Mon, 13 Mar 2023 15:49:09 +0100 [thread overview]
Message-ID: <20230313144916.511884-4-krzysztof.kozlowski@linaro.org> (raw)
In-Reply-To: <20230313144916.511884-1-krzysztof.kozlowski@linaro.org>
The FIMC camera node wrapper is not a bus, so using simple-bus fallback
compatible just to instantiate its children nodes was never correct.
Driver should explicitly populate all its children devices.
Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>

Changes since v1:
1. Do not depopulate on errors because it causes several errors.
