From 0cff593732fa5bdf07192be741a567b85a9c0cd3 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Fri, 25 Mar 2011 22:52:22 -0300 Subject: [PATCH] [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...
