Message-Id: <1330099282-4588-13-git-send-email-danny.kukawka@bisect.de> Date: Fri, 24 Feb 2012 17:01:22 +0100 From: Danny Kukawka <danny.kukawka@...ect.de> To: Ralf Baechle <ralf@...ux-mips.org> Cc: Danny Kukawka <dkukawka@...e.de>, "David S. Miller" <davem@...emloft.net>, linux-hams@...r.kernel.org, netdev@...r.kernel.org, linux-kernel@...r.kernel.org Subject: [PATCH 12/12] rose: check given MAC address, if invalid return -EADDRNOTAVAIL Check if given address is valid in .ndo_set_mac_address/ rose_set_mac_address(), if invalid return -EADDRNOTAVAIL as eth_mac_addr() already does if is_valid_ether_addr() fails.
