drm/nouveau: fix incorrect FB_BACKLIGHT usage in Kconfig
Making FB_BACKLIGHT tristate by commit b4a1ed0cd18b ("fbdev:
make FB_BACKLIGHT a tristate") caused unmet dependencies in
some configurations:
WARNING: unmet direct dependencies detected for FB_BACKLIGHT
Depends on [m]: HAS_IOMEM [=y] && FB [=m]
Selected by [y]:
- DRM_NOUVEAU [=y] && HAS_IOMEM [=y] && DRM [=y] && PCI [=y] && MMU [=y] && DRM_NOUVEAU_BACKLIGHT [=y]
Selected by [m]:
- FB_NVIDIA [=m] && HAS_IOMEM [=y] && FB [=m] && PCI [=y] && FB_NVIDIA_BACKLIGHT [=y]
Fix it by making DRM_NOUVEAU select BACKLIGHT_CLASS_DEVICE and
BACKLIGHT_LCD_SUPPORT instead of FB_BACKLIGHT.
Fixes: b4a1ed0cd18b ("fbdev: make FB_BACKLIGHT a tristate")
