HI Thomas,

Remove the field fb_blank from struct backlight_properties and remove
all code that still sets or reads it. Backlight blank status is now
tracked exclusively in struct backlight_properties.state.

The core backlight code keeps the fb_blank and state fields in sync,
but doesn't do anything else with fb_blank. Several drivers
initialize fb_blank to 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 rely on the state field.

Can you explain what are the differences between the version 1 and version

2 of the patch?

There are none. It's simply labeled v2 because it is part of the version
2 of this series.

...

Ah, ok. Sorry for my question, but having received only this email from the series,
I didn't understand why version two.
It's all clear now!

Best regards,
Flavio
