[Sascha Hauer <s.hauer@pengutronix.de>]

Changes since v1:

- Do not recurse into dependencies during slice_acquire
- detect recursice dependencies

  instead lock them individually

  net: fec_imx: Do not clear MII interrupt during receive
  miitool: Use mdiobus_read()
  net: phy: mdio-mux: Use mdiobus_read/write()
