  The write will be suppresed if the register contents don't
change which looks like what you're seeing here -

Can you imagine why the registers don't change?

I can't immediately think of any reason, no - I'd step through or
annotate the code and have a look.

I'm still on.

And while testing WM9712 its touchpad interface, connecting a 800x600
display (instead of the default 640x480 one) results in a gone sound and
input-device - pretty queer:

WM9711/WM9712 SoC Audio Codec 0.4
asoc: platform pcm constructor failed
asoc: can't create pcm HiFi
asoc: failed to instantiate card PhyCORE-ac97-audio: -12

I have to admit that I used this time a 3.2 kernel. I'll test with
current later these days.

Same behaviour with 3.4.0-rc6:

Framebuffer driver mx3fb configured for a 800x600 display:

  soc-audio soc-audio: ASoC machine PhyCORE-ac97-audio should use snd_soc_register_card()
  asoc: platform pcm constructor failed
  asoc: can't create pcm HiFi :-12
  asoc: failed to instantiate card PhyCORE-ac97-audio: -12


mx3fb configured for a 640x480 display:
  soc-audio soc-audio: ASoC machine PhyCORE-ac97-audio should use
  snd_soc_register_card()
  asoc: wm9712-hifi <-> imx-ssi.0 mapping ok
