Subject: [PATCH v2 0/1] i2c: Handle HAS_IOPORT dependencies

Hi,

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 branch[1]. As for compile-time vs runtime
see Linus' reply to my first attempt[2].

Thanks,
Niklas

Changes since v1:
- Removed HAS_IOPORT dependency for I2C_PARPORT as it could be used with MMIO
  based parallel port driver
