[PATCH v2 0/3] hw/i2c: smbus: Reset fixes

[Joe Komlodi]

Changelog:

v1 -> v2
- Dropped 4th patch "hw/i2c: smbus: mux: Reset SMBusDevice state
on reset". After more testing and Corey's comment, I realized it
wasn't needed.

Original message:

Hi all,

This series adds some resets for SMBus and for the I2C core. Along with
it, we make SMBus slave error printing a little more helpful.

These reset issues were very infrequent, they would maybe occur in 1 out
of hundreds of resets in our testing, but the way they happen is pretty
straightforward.

Basically as long as a reset happens in the middle of a transaction, the
state of the old transaction would still partially be there after the
reset. Once a new transaction comes in, the partial stale state can
cause the new transaction to incorrectly fail.

Thanks,
Joe
