There should probably be some sanity checks here that these function
pointers are non-NULL.
Yes I agree. Since with the current scpi driver, if scpi_ops is
populated, it's all non-NULL I skipped the sanity check as the probe
will check for non-NULL scpi_ops.
However, with extension work by Neil I agree, we may have to revisit all
such callers.
