Subject: soc: samsung: exynos-asv: don't defer early on not-supported SoCs
From: Marek Szyprowski <m.szyprowski@xxxxxxxxxxx>
commit 0458b88267c637fb872b0359da9ff0b243081e9e upstream.
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")
