3.2.95-rc1 review patch. If anyone has any objections, please let me know. ------------------ From: Dan Carpenter <dan.carpenter@xxxxxxxxxx> commit 6ebedacbb44602d4dec3348dee5ec31dd9b09521 upstream. If one of these kmalloc() calls fails then we return ERR_PTR(0) which is NULL. It results in a NULL dereference in the callers.
