Subject: net: dsa: Set valid phy interface type
X-Git-Tag: omap-for-v4.1/prcm-dts-mfd-syscon-fix~52^2
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=19334920eaf7df3f69950b040ede6c7598425a5b;p=pandora-kernel.git

net: dsa: Set valid phy interface type

If the phy interface mode is not found in devicetree, or if devicetree
is not configured, of_get_phy_mode returns -ENODEV. The current code
sets the phy interface mode to the return value from of_get_phy_mode
without checking if it is valid.

This invalid phy interface mode is passed as parameter to of_phy_connect
or to phy_connect_direct. This sets the phy interface mode to the invalid
value, which in turn causes problems for any code using phydev->interface.
