Subject: [ALSA] HDA: no sound in headphone-out caused by commit f889fa91ad47e (2.6.25-rc1 regression)

Hi,
after upgrading from 2.6.24 to 2.6.25-rc1, I lost headphone-out sound output 
of my Intel HDA card - it is quiet no matter what the mixer settings are.

After playing wit git bisect a bit, I narrowed it down to commit 
f889fa91ad47e "[ALSA] hda-codec - Improve the auto-configuration". [1]
It works okay with tree as of previous commit 69b1f1e8337fc9. 

First lines from /proc/asound/Intel/codec#0:
Codec: Realtek ALC262

Vendor Id: 0x10ec0262
Subsystem Id: 0x17340000

    bits [0xe]: 16 20 24
    formats [0x1]: PCM
Default Amp-In caps: N/A

GPIO: io=4, o=0, i=0, unsolicited=1, wake=0
  IO[0]: enable=0, dir=0, wake=0, sticky=0, data=0

  IO[2]: enable=0, dir=0, wake=0, sticky=0, data=0

The box is Fujitsu-Siemens Esprimo Mobile M9400 laptop.
