2 * gsmfr_preproc_good_frame_hm() is a wrapper around gsmfr_preproc_good_frame()
3 * that adds homing of the Rx DTX handler preprocessor block. This homing
4 * version of good frame preproc is not used in the full decoder (the latter
5 * implements its own homing logic as specified by 3GPP), but it will be used
6 * when our Rx DTX handler preprocessor functions as a TFO transform.
