Subject: ARM: dts: exynos: fix PWM LED max brightness on Odroid XU4
Git-commit: fd2f1717966535b7d0b6fe45cf0d79e94330da5f
Patch-mainline: v5.14-rc1
References: git-fixes

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")
