[PATCH v2 6/6] backlight: Remove fb_blank from struct backlight_properties

[FLAVIO SULIGOI]

Hi Thomas,

> FB_BLANK_UNBLANK to enable the backlight. This is already the default for
> the state field. So we can delete the fb_blank code from core and drivers and

Can you explain what are the differences between the version 1 and version 2 of the patch?
Thanks,
