Hi Arnd,

Thanks for your patch.

This adds a Kconfig dependency like we have it for some other panel drivers.

[PATCH 2/3] drm/panel: S6E3HA2 needs backlight code

2017-04-19 Thread Arnd Bergmann 
The new S6E3HA2 driver fails to link when backlight is disabled:

ERROR: "backlight_device_register" 
[drivers/gpu/drm/panel/panel-samsung-s6e3ha2.ko] undefined!
ERROR: "backlight_device_unregister" 
[drivers/gpu/drm/panel/panel-samsung-s6e3ha2.ko] undefined!

This adds a Kconfig dependency like we have it for some other panel drivers.
