staging: rtl8192u: r8192U_core: fix use ether_addr_copy() over memcpy() code style issue
Prefer ether_addr_copy() over memcpy() if the Ethernet addresses
are __aligned(2)
The values used are stored as dev_addr in net_device (declared in
include/linux/netdevice.h) and sa_data in sockaddr (declared in
include/linux/socket.h). Both these elements are u16 aligned as
shown by using pahole (position must be a multiple of sizeof(u16)):
unsigned char * dev_addr; /* 888 8 */
char sa_data[14]; /* 2 14 */
It is thus safe to use ether_addr_copy() instead of memcpy() for
that call, as it is already done in multiple files in the Linux
kernel sources:
