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

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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'.
