Subject: [PATCH v2 4/8] staging: r8188eu: use is_*_ether_addr() in rtw_macaddr_cfg()
Date: Mon, 30 Aug 2021 14:15:04 +0200 [thread overview]
Message-ID: <20210830121508.6411-5-straube.linux@gmail.com> (raw)
In-Reply-To: <20210830121508.6411-1-straube.linux@gmail.com>
Use is_broadcast_ether_addr() and is_zero_ether_addr() in
rtw_macaddr_cfg(). The buffer is properly aligned.
