Subject: [PATCH 3.16 058/294] IB/ipoib: Remove double pointer assigning

3.16.50-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Leon Romanovsky <leonro@...lanox.com>

commit 1b355094b308f3377c8f574ce86135ee159c6285 upstream.

There is no need to assign "p" pointer twice.

This patch fixes the following smatch warning:
drivers/infiniband/ulp/ipoib/ipoib_cm.c:517 ipoib_cm_rx_handler() warn:
	missing break? reassigning 'p->id'
