Subject: [PATCH] IB/qib: define max IB ports instead of variable stack allocation
Date: Wed, 02 Jun 2010 17:21:07 -0700 [thread overview]
Message-ID: <20100603002107.8958.18499.stgit@chromite.mv.qlogic.com> (raw)
Rather than use a variable size array allocation on the stack,
define a constant for the maximum array size possible.
