    kernel: i2c: Drop mentioning power management from the smbus slide
    
    I don't want to revert the commit because I think it still improves the
    definition by mentioning register-like interface, which is just our
    biased observation of the "command" interface (there is no register
    register read/write definition in the spec).

   \item SMBus is a subset of the I2C protocol.
-  \item It focuses on devices power management and defines a standard

   \item Linux provides SMBus functions that should preferably be used
     instead of the raw API with devices supporting SMBus.
   \item Such a driver will be usable with both SMBus and I2C adapters
