Subject: [PATCH rdma-next V1 01/17] IB/mad: Remove debug prints after allocation failure
Date: Thu,  3 Nov 2016 16:44:09 +0200	[thread overview]
Message-ID: <1478184265-9620-2-git-send-email-leon@kernel.org> (raw)
In-Reply-To: <1478184265-9620-1-git-send-email-leon-DgEjT+Ai2ygdnm+yROfE0A@public.gmane.org>

The prints after [k|v][m|z|c]alloc() functions are not needed,
because in case of failure, allocator will print their internal
error prints anyway.
