Commit-Message
From: Heiko Stuebner <heiko.stuebner@...> Commit 934624d6e9f0 ("regulator: gpio-regulator: do not open-code counting and access of dt array elements") forgot to convert the recently added gpios-states property using the same pattern. Convert this instance to use the of-helpers too, resolving the build error. Signed-off-by: Heiko Stuebner <heiko.stuebner@...>
