Subject: [PATCH 1/2] siw: Fix ib_register_device() for > v2.6.34 kernels

From: Nicholas Bellinger <nab@...ux-iscsi.org>

This patch adds a LINUX_VERSION_CODE > v2.6.34 check inside of siw_main.c:siw_register_device()
around the use of ib_register_device().  In post v2.6.34 kernels this function accepts a second
parameter used a sysfs port callback described here:

http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=9a6edb60ec10d86b1025a0cdad68fd89f1ddaf02

This patch currently sets this second parameter to NULL.
