/*
 * PMBUS_SKIP_STATUS_CHECK
 *
 * During register detection, skip checking the status register for
 * communication or command errors.
 *
 * 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.
