Subject: linux-next: build warning after merge of the net-next tree

Hi all,

After merging the net-next tree, today's linux-next build (x86_64
allmodconfig) produced this warning:

drivers/net/ethernet/xilinx/ll_temac_main.c: In function 'temac_set_multicast_list':
drivers/net/ethernet/xilinx/ll_temac_main.c:490:8: warning: 'i' may be used uninitialized in this function [-Wmaybe-uninitialized]
while (i < MULTICAST_CAM_TABLE_NUM) {
^

Introduced by commit
