cxgb4: Fix static checker warning
The patch e85c9a7abfa4: ("cxgb4/cxgb4vf: Add code to calculate T5 BAR2 Offsets for SGE Queue Registers") from Dec 3, 2014, leads to the following static checker warning: drivers/net/ethernet/chelsio/cxgb4/t4_hw.c:5358 t4_bar2_sge_qregs() warn: should '(qid >> qpp_shift) << page_shift' be a 64 bit type? This patch fixes it Signed-off-by: Hariprasad Shenai <hariprasad@chelsio.com> Signed-off-by: David S. Miller <davem@davemloft.net>
