[PATCH 0/1] Bluetooth: Handle HAS_IOPORT dependencies

[Niklas Schnelle]

Hi Marcel, Luiz,

This is a follow up in my ongoing effort of making 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 a significant
subset of patches merged I've changed 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 final
patch that will make the I/O port accessors compile-time optional.

The current state of the full series with changes to the remaining
subsystems and the aforementioned final patch can be found for your
convenience on my git.kernel.org tree in the has_ioport_v6 branch[1] with
signed tags. As for compile-time vs runtime see Linus' reply to my first
attempt[2].

Thanks,
Niklas

[PATCH 1/1] Bluetooth: add HAS_IOPORT dependencies

[Niklas Schnelle]

In a future patch HAS_IOPORT=n will disable inb()/outb() and friends at
compile time. We thus need to add HAS_IOPORT as dependency for those
drivers using them.
