Subject: [PATCH net-next 0/2] mv88e6xxx: Avoid false positive Lockdep splats

When acquiring the GPIO interrupt line for the switch, it is possible
to trigger lockdep splats. These are false positives, the mutex is in
a different IRQ descriptor. But fix it anyway, since it could mask
real locking issues.

  net: dsa: mv88e6xxx: Add lockdep classes to fix false positive splat
