Merge branch 'net-phy-Unbind-fixes'
Florian Fainelli says: ==================== net: phy: Unbind fixes This patch series fixes a couple of issues with the unbinding of the PHY drivers and then bringing down a network interface. The first is a NULL pointer de-reference and the second was an incorrect warning being triggered. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
