[alsa-devel] hdspm.c - confused about SNDRV_HDSPM_IOCTL_GET_[CONFIG|STATUS]

i'm trying to extend hdspconf to work with the rme hdspm madi card, and
got confused over the snd_hdspm_hwdep_ioctl:
apparently, the hdspm.c driver differentiates between settable controls
(CONFIG) and non-settable status indicators (STATUS), unlike the earlier
however, usage seems a bit inconsistent:
struct hdspm_config contains a member madi_sync_check, which is
apparently never set.
instead, struct hdspm_status card_specific.sync_madi is used, same for
tco and sync in.
but there is a wordclock_sync_check in struct hdspm_config which is in use.
am i guessing right that the latter is somewhat deprecated and that i
should be taking all status values from struct hdspm_status instead?
please cc: me, i'm not on alsa.devel.
