The rename of corgibl_limit_intensity is missed in commit d00ba726
"backlight: Rename the corgi backlight driver to generic".
Let's fix it now.

Why does corgibl_limit_intensity/genericbl_limit_intensity exist?
Nothing in the tree references it?

It sounds like someone has removed the sharpsl battery driver which did
use this. If this hook isn't used, low battery with high screen
backlight values will reset the device as the wiring isn't up to the
current draw.

It is removed by commit 13a542475d1c62a12c77abfa83a790245598fc61
Author: Christoph Egger <siccegge@cs.fau.de>
Date: Sun Jul 4 23:24:52 2010 +0800
[ARM] pxa: removing dead BACKLIGHT_CORGI
BACKLIGHT_CORGI was later renamed to BACKLIGHT_GENERIC and has not been
used since then. As it's now safe to completely transition to LCD_CORGI
driver, which incorprates both the LCD and backlight device.

So, should we remove corgibl_limit_intensity/genericbl_limit_intensity
since now it is not being used?

Does that code workaround the hardware issue I mention? I suspect not.
It seems nobody cares about that at this point though...
Cheers,
