Subject: [PATCH net 0/3] net: dsa: microchip: Fix resource releases in
 error path

Hi all,

I worked on adding PTP support for the KSZ8463. While doing so, I ran
into a few bugs in the resource release process that occur when things go
wrong arount IRQ initialization.

This small series fixes those bugs.

The next series, which will add the PTP support, depend on this one.
