Subject: staging: vt6656: Use ether_addr_copy() in vnt_fill_ieee80211_rts.
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=ccc103f564d992bb3260a9195980b26098384943;p=deliverable%2Flinux.git

staging: vt6656: Use ether_addr_copy() in vnt_fill_ieee80211_rts.

Both struct ieee80211_rts and struct ieee80211_hdr defined in
linux/ieee80211.h are declared as __aligned(2) so it is safe to use
ether_addr_copy() instead of memcpy().
