SMBus has that timeout, but I2C doesn't. How about disabling the timeout
simply? Or using the max value if you want to keep the timeout
detection?

Disabling the timeout seems fine to me.  We still have a 1-second
timeout around the entire transfer.  I'll be back on my DSI branch this
week and test it out then.
