From c6d6a511d768cf7627ab54fc18f40edf85097362 Mon Sep 17 00:00:00 2001 From: Lennert Buytenhek Date: Thu, 18 Sep 2008 03:06:52 +0000 Subject: phylib: phy_mii_ioctl() fixes Make the SIOCGMIIPHY case fall through properly (it is supposed to not only return the ID of the default PHY but also to read from that PHY), and make phy_mii_ioctl() return the same error code as generic_mii_ioctl() in case of an unsupported operation.
