[PATCH] Fix error handling in backlight drivers

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi Jamey, Andrew,

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.
