Re: [PATCH 3/6] [media] pvrusb2: check for allocation failures
I'll look at the surrounding code and see what makes sense there. Having an error leg for allocation failures is a useful thing. -Mike Dan Carpenter wrote: On Fri, Mar 25, 2011 at 11:33:36PM -0500, Mike Isely wrote: Acked-By: Mike Isely is...@pobox.com I'd need to reformat this one to get it to apply... :/ It doesn't actually fix the bug so it's not worth it. regards, dan carpenter -- To unsubscribe from this list: send the line unsubscribe linux-media in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html -- Mike Isely isely @ isely (dot) net PGP: 03 54 43 4D 75 E5 CC 92 71 16 01 E2 B5 F5 C1 E8 -- To unsubscribe from this list: send the line unsubscribe linux-media in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
[PATCH 3/6] [media] pvrusb2: check for allocation failures
This function returns NULL on failure so lets do that if kzalloc() fails. There is a separate problem that the caller for this function doesn't check for errors...
