[PATCH 1/1] arm64: defconfig: enable backlight device class

[PATCH 1/1] arm64: defconfig: enable backlight device class

[Alexander Stein]

CONFIG_DRM_PANEL_SIMPLE is enabled in this config. But it depends on
CONFIG_BACKLIGHT_CLASS_DEVICE which is only transitively enabled by
DRM_NOUVEAU, iff DRM_NOUVEAU_BACKLIGHT is enabled as well.
As simple-panel depends on backlight, enable this in defconfig as well.

Fine by me. But this is not SoC-specific rather than a general change.
So who should be addressed then?

Best regards
