Subject: net: phy: add genphy_aneg_done()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a9fa6e6ac29709e7a623b60695c172da675df045;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

net: phy: add genphy_aneg_done()

In preparation for allowing PHY drivers to potentially override their
auto-negotiation done callback, move the contents of phy_aneg_done() to
genphy_aneg_done() since that function really is the generic
implementation based on the BMSR_ANEGCOMPLETE status.
