Subject: A potential bug in drivers/net/ethernet/synopsys/dwc_eth_qos.ko

Hi!

There is a potential bug in 
drivers/net/ethernet/synopsys/dwc_eth_qos.ko. In dwceqos_probe there is 
a registration of net device (line 2879). After that initialization of 
common resources is continued (lines 2918, 2924, 2941), but at the 
moment handlers from net device may be already executed.

Should the registration of net device be at the end of dwceqos_probe?
