From: Stephen Hemminger Date: Fri, 2 Feb 2007 16:22:51 +0000 (-0800) Subject: skge: handle zero address at open X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=fae87592280039837fdd72c5ecdac2af2eb97f63;p=linux-beck.git skge: handle zero address at open Some motherboards are broken and have no address set. Failing at probe time prevents the device from ever being used (like to download a fixed BIOS). Instead warn on probe and check again when device is brought up. That way the address can be set.
