Still it doesn't rectify.

Then such info isn't appropriate to be static.  If it's dynamic,
this has to be provided via other interface.

BTW, now I get the following warnings:
  sound/pci/rme9652/hdspm.c:578:14: warning: ‘texts_sync_status’ defined but not used
  sound/pci/rme9652/hdspm.c:695:13: warning: ‘channel_map_unity_ds’ defined but not used
  sound/pci/rme9652/hdspm.c:706:13: warning: ‘channel_map_unity_qs’ defined but not used
  sound/pci/rme9652/hdspm.c: In function ‘snd_hdspm_hwdep_ioctl’:
  sound/pci/rme9652/hdspm.c:6141:1: warning: the frame size of 2464 bytes is larger than 1024 bytes

Care to fix it?
