That definition makes sense to me. With it, the read before the write
is fine: an uncached FORCE_SET control is one the device can read.

I also prefer the current return value. If a put always returned 1,
the kernel would send a change event even when alsactl restores an
unchanged value. So I dropped my diff. Patch 10 has only the comment
typo fixed and the blank line removed.

Right, they add only table entries, the device ID and the map lines.
They are now one patch (15 of this series).

Thanks, here it is: your 11 RFC V2 patches, then the five iD14
patches. It sits on top of your four mixer_evo fixes. I can rebase
it once Takashi decides how those go in.

Patches 12 to 16:
- 12 adds a step size to integer controls (the iD14 volumes move in
  1 dB steps).
- 13 adds enumerated controls (routing, iD key function, talkback
  source, digital input mode).
- 14 gives the iD14 MkI its own mixer map; the MkII keeps the shared
  one.
- 15 adds the iD14 MkI controls: monitor section, routing, mixer
  matrix and the write-only controls.
- 16 replaces the generic FU 12 control, whose GET returns stale data.

Base: sound master 603a4df9e6ae with your four fixes (Patchwork series
1193966). Each patch builds on its own with W=1 without warnings. On
an iD14 MkI (7.2.11 stable), the complete series passed the same read
and write checks as RFC V2, change events included.

Thanks,
Will
