which is the vast majority of them.  The adapters that don't have their
own ->smbus_xfer() fall back on the ->master_xfer() through the emulated
transfer).

The special case is iop3xx, which has more than its fair share of hacks
within this driver, it remains untested -- though also claims to support
emulated SMBus accesses.  The corner case there is rs5c_get_regs() which
uses access mode #3 for transferring the register state, while we use mode
#1 for SMBus.
