Subject: staging: rtl8723bs: remove custom is_multicast_mac_addr() function
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=2541d1822954b6629cf4bbc0d20fea82143452b3;p=thirdparty%2Fkernel%2Fstable.git

staging: rtl8723bs: remove custom is_multicast_mac_addr() function

is_multicast_mac_addr() is redundant reimplementation of standard
is_multicast_ether_addr() func.
Remove it and switch to use is_multicast_ether_addr().
