Subject: [PATCH 0/9] Clause 45 PHY probing improvements


Last time this series was posted back in May, Florian reviewed the
patches, which was the only feedback I received.  I'm now posting
them without the RFC tag.

This series aims to improve the probing for Clause 45 PHYs.

The first four patches clean up get_phy_device() and called functions,
updating the kernel doc, adding information about the various error
return values.

We then provide better kerneldoc for get_phy_device(), describing what
is going on, and more importantly what the various return codes mean.

Patch 6 adds support for probing MMDs >= 8 to check for their presence.

Patch 7 changes get_phy_c45_ids() to only set the returned
devices_in_package if we successfully find a PHY.

Patch 8 splits the use of "devices in package" from the "mmds present".

Patch 9 expands our ID reading to cover the other MMDs.
