Subject: [ofa-general] [PATCH] IB/core - remove redundant NULL pointer
check in ib_mad_recv_done_handler()
Date: Wed, 17 Oct 2007 18:06:42 -0700

In ib_mad_recv_done_handler(), the response pointer is checked for
NULL after allocating it.  It is then checked again in the local
process_mad() path but there is no possibility of it changing
in between.
