Wei Yongjun 9047fa5d32 phy: phy-ocelot-serdes: fix return value check in serdes_probe() 
In case of error, the function syscon_node_to_regmap() returns ERR_PTR()
and never returns NULL. The NULL test in the return value check should
be replaced with IS_ERR().

Fixes: 51f6b410fc ("phy: add driver for Microsemi Ocelot SerDes muxing")

Quentin Schulz 51f6b410fc phy: add driver for Microsemi Ocelot SerDes muxing 
The Microsemi Ocelot can mux SerDes lanes (aka macros) to different
switch ports or even make it act as a PCIe interface.

This adds support for the muxing of the SerDes.
