Which is fine until you meant a mux or a device that can be moved about
by writing to it, or has a wide range of addre

Correct - I've heard the same issues that reads on I2C can be misinterpreted
as writes ... and oops, you have a brick.

previous feedback about using I2C to talk with the DIMM).

Hmm, after thinking about it for a while an
Add i2c_scan_dimm_bus to declare that a particular i2c_adapter
contains DIMMs. This will probe (and autoload modules!) for useful
SMBUS devices that live on DIMMs. i2c_imc calls it.
As more SMBUS-addressable DIMM components become supported, this
code can be extended to probe for them.
