Subject: [PATCH 0/3] usb: pci-quirks: Handle HAS_IOPORT depenedencies

Hi Greg, Hi Mathias,

This is a follow up to my ongoing effort of making the inb()/outb() and
similar I/O port accessors compile-time optional. Previously I sent this
as a treewide series titled "treewide: Remove I/O port accessors for
HAS_IOPORT=n" with the latest being its 5th version[0]. With about half
of the per-subsystem patches merged I'm changing over to per-subsystem
series. These series are stand alone and should be merged via the
relevant tree such that with all subsystems complete we can follow this
up with the last patch[1] that will make the I/O port accessors
compile-time optional.

As for compile-time vs runtime see Linus' reply to my first attempt[2].

This series is for the USB subsystem and incorporates the feedback
received for the previous single patch USB subsystem change. In
particular I split things up in a preparatory code movement patch
followed by two independent patches for adding the HAS_IOPORT handling.
As the pci-quirks.c and hcd-pci.c files handle a diverse set of devices
I sadly couldn't get around ifdeffery but at least now it's contained in
smaller patches.

Thanks,
Niklas
