net: sgi: use GFP_ATOMIC under spin lock
The function meth_init_tx_ring() is called from meth_tx_timeout(), in which spin_lock is held, so we should use GFP_ATOMIC instead. Fixes: 8d4c28fbc284 ("meth: pass struct device to DMA API functions") Signed-off-by: Wei Yongjun <weiyongjun1@huawei.com> Signed-off-by: David S. Miller <davem@davemloft.net>
