[PATCH net-next 0/4] net: phy: clean up phy.h

[Heiner Kallweit]

This series is a starting point to clean up phy.h and remove
definitions which are phylib-internal.

Heiner Kallweit (4):
  net: phy: remove fixup-related definitions from phy.h which are not
    used outside phylib
  net: phy: stop exporting feature arrays which aren't used outside
    phylib
  net: phy: stop exporting phy_queue_state_machine
  net: phy: remove helper phy_is_internal

[PATCH net-next 1/4] net: phy: remove fixup-related definitions from phy.h which are not used outside phylib

[Heiner Kallweit]

Certain fixup-related definitions aren't used outside phy_device.c.
So make them private and remove them from phy.h.

Overall looks like a nice cleanup but I am not sure about this space
between #define and PHY_ANY_ID or PHY_ANY_UID...

There's a tab, which effectively equals a space. Maybe it's just the
diff which is misleading. At least checkpatch didn't complain.
