[PATCH 8/9] staging: ks7010: Remove 'eth_addr' field from 'struct ks_wlan_private'.

Quytelda Kahja
2018-03-29T05:51:51Z

The ethernet address of the network device is already stored in the
'dev_addr' field of 'struct net_device'. Since 'struct ks_wlan_private'
keeps a pointer to the driver's 'struct net_device', there is no reason
to duplicate this information in 'struct ks_wlan_private'.
