From bfd2793c9559ae73ae021797f1d4b097c27f24be Mon Sep 17 00:00:00 2001 From: Yann Droneaud <[mailto:ydroneaud@opteya.com]> Date: Fri, 28 Mar 2014 14:55:21 -0400 Subject: [PATCH] RDMA/cxgb4: set error code on kmalloc() failure If kmalloc() fails in c4iw_alloc_ucontext(), the function leaves but does not set an error code in ret variable: it will return 0 to the caller. This patch set ret to -ENOMEM in such case. Cc: Steve Wise Cc: Steve Wise Signed-off-by: Yann Droneaud Acked-by: Steve Wise Signed-off-by: David S.
