Subject: phy: mdiobus_register(): initialize all phy_map entries
X-Git-Tag: v2.6.17-rc4~8^2~2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=64b1c2b42b555ef38c475d104f2faf3f6f93690d;p=platform%2Fkernel%2Flinux-stable.git

phy: mdiobus_register(): initialize all phy_map entries

make sure phy_map entries whose PHY address is masked are initialized
to NULL, given that other code (such as mdiobus_unregister for
instance) assumes that non-NULL phy_map entries are allocated
phy_devices
