[RFC,09/17] ASoC: codecs: hda: Switch to new stream-format interface

Commit Message

Cezary Rojewski Aug. 11, 2023, 4:48 p.m. UTC

To provide option for selecting different bit-per-sample than just the
maximum one, use the new format calculation mechanism.

While at it, complete PCM stream initialization with subformat options.
