====================
net: phy: mscc: multiple improvements

This series contains various improvements to the MSCC PHY driver, fixing
sparse and smatch warnings, using functions provided by the PHY core,
and improving the driver consistency and maintenance.

I don't think any of those improvements and fixes is worth backporting
to stable trees.
