Store the display's blank status in struct fb_info.blank and track it in fb_blank(). As an extra, the status is now available from the sysfs blank attribute. Support for blanking is optional. Therefore framebuffer_alloc() initializes the state to FB_BLANK_UNBLANK (i.e., the display is on). If the fb_blank callback has been set, register_framebuffer() sets the state to FB_BLANK_POWERDOWN. On the first modeset, the call to fb_blank() will update it to _UNBLANK. This is important, as listeners to FB_EVENT_BLANK will now see the display being switched on.
