Subject: [PATCH] staging: r8188eu: replace custom hwaddr_aton_i() with mac_pton()
Date: Thu, 12 Aug 2021 15:20:57 +0200	[thread overview]
Message-ID: <20210812132057.22579-1-straube.linux@gmail.com> (raw)

Replace custom hwaddr_aton_i() with mac_pton() in core/ioctl_linux.c
and remove the now unused functions hwaddr_aton_i() and hex2num_i().
