Subject: [PATCH] Fix error handling in backlight drivers
Date: Sun, 5 Mar 2006 19:08:49 +0100 [thread overview]
Message-ID: <20060305190849.03877211.khali@linux-fr.org> (raw)
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.
