Subject: net: phy: fix a bug when verify the EEE support
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=9a9c56cb34e65000d1f0a4b7553399bfcf7c5a52;p=openwrt%2Fstaging%2Fblogic.git

net: phy: fix a bug when verify the EEE support

The phy_init_eee has to exit with an error when the
local device and its link partner both do not support EEE.
So this patch fixes a problem when verify this.
