[PATCH v2 1/4] soc: samsung: exynos-asv: don't defer early on not-supported SoCs
From: Krzysztof Kozlowski
Date: Mon Dec 07 2020 - 14:06:29 EST
From: Marek Szyprowski <m.szyprowski@xxxxxxxxxxx>
Check if the SoC is really supported before gathering the needed
resources. This fixes endless deferred probe on some SoCs other than
Exynos5422 (like Exynos5410).
Fixes: 5ea428595cc5 ("soc: samsung: Add Exynos Adaptive Supply Voltage driver")
