Subject: [PATCH 4.19 400/421] ARM: dts: exynos: fix PWM LED max brightness on Odroid XU4

From: Krzysztof Kozlowski <krzysztof.kozlowski@...onical.com>

[ Upstream commit fd2f1717966535b7d0b6fe45cf0d79e94330da5f ]

There is no "max_brightness" property as pointed out by dtschema:

  arch/arm/boot/dts/exynos5422-odroidxu4.dt.yaml: led-controller: led-1: 'max-brightness' is a required property

Fixes: 6658356014cb ("ARM: dts: Add support Odroid XU4 board for exynos5422-odroidxu4")
