Subject: [PATCH net 0/7] net: stmmac: fix probe error handling and phydev leaks

This series fixes a number of issues with the stmmac-driver probe error
handling, which for example left clocks enabled after probe failures.

The final patch fixes a failure to deregister and free any fixed-link
PHYs that were registered during probe on probe errors and on driver
unbind. It also fixes a related of-node leak on late probe errors.

This series depends on the of_phy_deregister_fixed_link() helper that
was just merged to net.

As mentioned earlier, one staging driver also suffers from a similar
leak and can be fixed up once the above mentioned helper hits mainline.

Note that these patches have only been compile tested.
