From f0c6e88288d65c93bbc7da4fb6f7d51b2733228a Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Thu, 13 Jul 2017 10:46:49 +0300 Subject: [PATCH] RDMA/ocrdma: Fix error codes in ocrdma_create_srq() If either of these allocations fail then we return ERR_PTR(0). That's equivalent to NULL and results in a NULL pointer dereference in the caller.
