[PATCH V6 0/2] virtio: i2c: Allow zero-length transactions

[Viresh Kumar <viresh.kumar@linaro.org>]

Hi,

This patchset simplifies the protocol and allows zero-length transactions, which
are required to support stuff like: i2cdetect -q <i2c-bus-number>, which issues
a zero-length SMBus Quick command.

V5->V6:
- s/SMBus Quick/the SMBus "Quick" command/
- Add a footnote and reword/rearrange few parts for more clarity.

V4->V5:
- Split into two patches.

V3->V4:
- Add a new mandatory feature flag.

V2->V3:
- Add conformance clauses that require that the flag is consistent with the
  buffer.

V1->V2:
- Name the buffer-less request as zero-length request.
