[PATCH net v3 0/3] net: phy: Fix PHY module checks and NULL deref in phy_attach_direct()

[Florian Fainelli <f.fainelli@gmail.com>]

Hi all,

This patch series addresses the crash seen with the Generic PHY driver
in phy_attach_direct() introduced in the latest pull to Linus.

We also address how to properly bind and unbind to/from the PHY drivers which
would previously be crashing in flames since we did not stop the state machine.

Thanks!

Changes in v3:

- made more testing as module/built-in, with Generic and non-Generic PHY drivers
- exercised error paths on purpose by injecting errors
- properly incremenet Generic PHY module reference count as well
- fixed the error path to be correct

Changes in v2:

- fixed net: phy: Fix lack of reference count on PHY driver against
  the Generic PHY driver which is special
