Subject: net: phy: modify assignment to OR for dev_flags in phy_attach_direct
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=e7312efbd5dec50d791dd98bd92ec9ae4f05a832;p=openwrt%2Fstaging%2Fblogic.git

net: phy: modify assignment to OR for dev_flags in phy_attach_direct

Modify the assignment to OR when dealing with phydev->dev_flags in
phy_attach_direct function, and this is to make sure dev_flags set in
driver's probe callback won't be lost.
