ret1 is non-descriptive in this context. Renaming it to reflect the operation (e.g. ret_disable) would make the error-handling logic easier to follow and reduce the chance of mistakes during future edits.

hda_data_stream_cleanup() now returns an error if the SPIB reset/disable fails, which changes behavior for capture streams (previously ret stayed 0 unless direction was PLAYBACK). Since SPIB appears optional and other call sites treat SPIB config as best-effort (e.g. hda_dsp_stream_hw_free() calls hda_dsp_stream_spib_config(...DISABLE...) and still returns 0 at hda-stream.c:770-774), consider not propagating SPIB failures from cleanup (e.g. only attempt when sdev->bar[HDA_DSP_SPIB_BAR] is present, and/or keep ret at 0 unless later cleanup steps fail).
