[2.6 patch] Fix error handling in backlight drivers

[Adrian Bunk]

From: Jean Delvare <khali@linux-fr.org>

I have spotted the following problem in the way the backlight and lcd
drivers handle out-of-memory errors. This should probably be fixed for
2.6.16. Note that I don't have supported hardware so I couldn't
actually test the fix.


ERR_PTR() is supposed to be passed a negative value.
