Fix the parsing of check of pattern ethernet-phy-ieee802.3 used
by the device tree to initialize the mdio phy.

As per the of_mdio below 2 are valid compatible string
      "ethernet-phy-ieee802.3-c22"
      "ethernet-phy-ieee802.3-c45"

Nope, this is not the full story. Yes, you can have these compatible
strings. But you can also use the PHY ID,
e.g. ethernet-phy-idAAAA.BBBB, where AAAA and BBBB are what you find in
registers 2 and 3 of the PHY.

Oops I did not read the drivers/net/mdio/of_mdio.c completely.
Thanks for letting me know so in the next series,
I will try to add the below compatible string as per the description in the dts.

               compatible = "ethernet-phy-id001c.c916",
                            "ethernet-phy-ieee802.3-c22";

So here you need, in addition to, not instead of.

Please test you change on for example imx6ul-14x14-evk.dtsi

Yes I have gone through the test case.
