Quoting Gabor Juhos (2024-02-29 10:07:51)
> The frequency table arrays are supposed to be terminated with an
> empty element. Add such entry to the end of the arrays where it
> is missing in order to avoid possible out-of-bound access when
> the table is traversed by functions like qcom_find_freq() or
> qcom_find_freq_floor().
> 
> Only compile tested.
