Subject: [PATCH v3 0/3] ASoC: add support for audio on iPaq hx4700

Ok, here's another version of patches adding audio support for good ole
iPAQ hx4700. It took a bit faster to make v3 than I expected, so here is it.

Previous versions can be found here:
https://lkml.org/lkml/2010/11/20/50 (v1)
https://lkml.org/lkml/2011/5/16/462 (v2)

This patchset is based on 'for-next' branch of Mark's ASoC git tree
(fetched today), also applies cleanly on linux-next-20110518.
Lightly tested on real hardware - playback/recording/mixer seem to work
without any glitches.

Changes v2 -> v3

* data based init is now used in codec and machine audio driver
  for DAPM and controls
* machine audio driver now is a proper platform driver, instantiating
  sound card with snd_soc_register_card()
* platform code registers corresponding platform_device for machine audio driver
* ak4641_sync() is dropped in favour of snd_soc_cache_sync()
* snd_soc_update_bits() is used instead of snd_soc_read()/update/snd_soc_write()
  sequences. Also return value of snd_soc_update_bits is propagated further
  for catching errors (previously result of snd_soc_write wasn't checked)
* gpio_request_array is used now in machine audio driver
* some other minor cleanup in the couple of places
