* Some PMBus chips respond with valid data when trying to read an unsupported
* register. For such chips, checking the status register is mandatory when
* trying to determine if a chip register exists or not.
* Other PMBus chips don't support the STATUS_CML register, or report
* communication errors for no explicable reason. For such chips, checking
* the status register must be disabled.
