Subject: [PATCH 1/7] staging: rtl8188eu: use is_broadcast_ether_addr
Date: Tue, 31 Jul 2018 13:34:09 +0200 [thread overview]
Message-ID: <20180731113415.1500-1-straube.linux@gmail.com> (raw)
Use is_broadcast_ether_addr instead of checking each byte of the
address array for 0xff. Shortens the code and improves readability.
As required by is_broadcast_ether_addr, the address array sta_addr
is properly aligned in all uses. Thanks to Joe Perches.
