Looks like this was never needed for anything else but to potentially find bugs where the filter is accessed uninitialized. For that purpose it could still be valid there.

@jsarha it is now inside the asrc_free_polyphase_filter() function and I think it can be needed when called from asrc_set_fs_ratio()

because of #9845 I cannot run-time test this, so perhaps it's better to not merge it before it's been tested |

Waiting for thesofproject/linux#5335 to be merged |
