44c10138fd PCI: Change all drivers to use pci_device->revision
Instead of all drivers reading pci config space to get the revision
ID, they can now use the pci_device->revision member.

This exposes some issues where drivers where reading a word or a dword
for the revision number, and adding useless error-handling around the
read. Some drivers even just read it for no purpose of all.

In devices where the revision ID is being copied over and used in what
appears to be the equivalent of hotpath, I have left the copy code
and the cached copy as not to influence the driver's performance.

Compile tested with make all{yes,mod}config on x86_64 and i386.

897cc188f7 [ALSA] hda-codec - Fix STAC922x capture boost level
STAC922x provides the capture boost level up to 4, but actually it
works only up to 2.  Since the range of the mixer is automatically
defined from amp-capability bits, we need to override the value
beforehand.  snd_hda_override_amp_caps() is introduced for this
purpose.
The function patch_stac922x() calls this for NID 0x12 (Mux Capture
Volume).  This should fix another recording problem on Intel Macs.

carried over.
This patch allows affected users to use audio again.

7b04389999 [ALSA] hda-codec - bug fixes for stac92xx HDA codecs.
* fixed surround playback on stac922x. Pin direction control bits were
  not being set correctly in stac92xx_set_pinctl(). Specifically it
  would refuse to set the port as an output if the port was already
  configured as an input. Last hunk (#8).
* fixed an input mux bug on 92xx codecs. When there is more than one
  possible input calculated for the muxes, the actual mux widget never
  gets set from its reset default, which is index 0, in the stac9221
  case that is port E. So alsamixer/amixer/gnome-mixer report the Mic
  as being the selected input source, but in fact is something else
  (line-in port E in stac9221 case). Another problem with this is that
  if you actually try to set the mux input to 'Mic', nothing happens
  because *cur_val == idx (see snd_hda_input_mux_put). You have to
  actually toggle input source to line-in then back to mic to actually
  set the mux widget. Hunk #7.
* fixed some typos in patch_sigmatel.c. Hunk #6.
* fix to stac92xx_add_dyn_out_pins() that fixes surround playback on
  codecs with less that 4 DACs (stac9205 for example). It reads the widget
  caps cache created by hda_codec to count the total number of analog DACs
  found. It then uses that to determine whether there will be enough
  independent DACs available for line/mic switch controls. Hunk #1, #2,
  and #3.
* improvements to stac92xx_auto_fill_dac_nids() to make it more general.
  This fixes surround playback on some codecs in combination with the
  fix to stac92xx_add_dyn_out_pins() above. It reads the full connection
  list now, instead of just the first entry, and then locates an analog
  DAC in the list. If one is found and it's free, assign it to that line-out.
  If no free DAC is found for the line-out, return -ENODEV. It also makes
  sure to actually select the chosen DAC if more than one DAC is input to
  the pin. Hunks #4, #5.

a961f9fe8c [ALSA] hda-codec - Add support of 96kHz back
Added the support of 96kHz sample rate back.  Although the rate isn't
listed in the ACC_PAR_PCM bits but si3054 codecs do support this rate
explicitly.  Now fixed the deteciton code not to check this extra bit.
