staging: rtl8188eu: hal: rtl8188e_cmd: Use ether_addr_copy() instead of memcpy()
The checkpatch.pl found the warning: WARNING: Prefer ether_addr_copy() over memcpy() if the Ethernet addresses are __aligned(2) Checked if the the Ethernet addresses are __aligned(2) by using pahole tool. The type of pwlanhdr is struct ieee80211_hdr and pahole shows that addr1, addr2, and addr3 are aligned to u16. struct ieee80211_hdr { __le16 frame_control; /* 0 2 */ __le16 duration_id; /* 2 2 */ u8 addr1[6]; /* 4 6 */ u8 addr2[6]; /* 10 6 */ u8 addr3[6]; /* 16 6 */ __le16 seq_ctrl; /* 22 2 */ u8 addr4[6]; /* 24 6 */ /* size: 30, cachelines: 1, members: 7 */ /* last cacheline: 30 bytes */ }; Both eeprompriv from struct adapter and MacAddress from struct wlan_bssid_ex have the offset multiple of sizeof(u16). Also, the array bc_addr and the pointers: StaAddr, mac, and bssid, start from an even offset.
