fc084e0b93 ALSA: sis7019 - give slow codecs more time to reset
There are some AC97 codec and board combinations that have been observed
to take a very long time to respond after the cold reset has completed.
In one case, more than 350 ms was required. To allow users to have sound
on those platforms, we'll wait up to 500ms for the codec to become
ready.

As a board may have multiple codecs, with some faster than others to
reset, we add a module parameter to inform the driver which codecs
should be present.

88d686027b ALSA: hda - Fix S3/S4 problem on machines with VREF-pin mute-LED
The verb command in stac92xx_post_suspend caused the audio to stop
working after resuming from S3 mode on HP laptops with the VREF-pin
mute-LED control.  Removing relevant post_suspend registering.

Although removing D3 on AFG is no optimal solution, the impact should
be small in comparison with the broken S3/S4.

4f8b6c7dc8 ALSA: hda_intel - revert a quirk that affect VIA chipsets
This quirk sould be reverted. It has the following probems:

1) The quirk was intended to "ASUS MV2-MX SE" motherboards only, but the
ID used matches a much broader range, potentially all boards containing a
VIA chipset model in the family of vendor VIA 0x1106 and audio device ID
0x3288, which encompasses VIA-VT82xx, VIA-VT1xx and VIA-VT20xx chipsets.

2) VIA chipsets rely on azx_via_get_position() to handle correctly dma
transfers during capture. Using POS_FIX_LPIB instead of POS_FIX_VIACOMBO
leads to partially corrupted input buffers during capture. The effects
of this bug are not immediately visible, it took strong DSP expertise,
some expensive signal generator and a spectrum analyzer to identify it
and verify correct behaviour using original default.

3) It's almost certain that the quirk did not fix the real problem,
if there was one. Refer to original submission:

187d333edc ALSA: hda - Fix jack-detection control of VT1708
VT1708 has no support for unsolicited events per jack-plug, the driver
implements the workq for polling the jack-detection.  The mixer element
"Jack Detect" was supposed to control this behavior on/off, but this
doesn't work properly as is now.  The workq is always started and the
HP automute is always enabled.

This patch fixes the jack-detect control behavior by triggering / stopping
the work appropriately at the state change.  Also the work checks the
internal state to continue scheduling or not.

6759dc3238 ALSA: hda/realtek - Fix missing inits of item indices for auto-mic
When the imux entries are rebuilt in alc_rebuild_imux_for_auto_mic(),
the initialization of index field is missing.  It may work without it
casually when the original imux was created by the auto-parser, but
it's definitely broken in the case of static configs where no imux was
parsed beforehand.  Because of this, the auto-mic switching doesn't
work properly on some model options.

This patch adds the missing initialization of index field.

6dfeb703e3 ALSA: hda - Fix invalid pin and GPIO for Apple laptops with CS codecs
The PCI SSID 8086:7270 is commonly used for multiple Apple machines,
thus we can't use it as identifier for a unique model.  Because of this
conflict, some machines show weird behavior.  For example, MacBook Air
shows Front and Surround speakers although only Surround works due to
the wrongly overridden pin-configuration for imac27.

This patch fixes two things:
- Stop the wrong pin-config override of imac27 by removing PCI SSID
  entry for avoiding the wrong mappings,
- Add the generic GPIO setup for Apple machines by checking the codec
  SSID vendor bits

2f451d2a2a ALSA: hda - Re-enable the check NO_PRESENCE misc bit
We disabled the check of NO_PRESENCE bit of the default pin-config
in commit f4419172 temporarily.  One problem was that the first
implementation was wrong -- the bit after the shift must be checked.
However, this would still give many regressions on machines with broken
BIOS.  They set this bit wrongly even on active pins.

A workaround is to check whether all pins contain this bit.  As far as
I've checked, broken BIOSen set this bit on all pins, no matter whether
active or not.  In such a case, the driver should ignore this bit check.

stream appropriately.

359f90982c ALSA: hda_hwdep: Fix possible buffer overflow
If a line in the firmware file is larger than the given buffer size (and
so the firmware file size), size is set to a value larger than the actual
buffer size. This results in an overflow in the buffer passed.

d81a6d7176 sound: Add export.h for THIS_MODULE/EXPORT_SYMBOL where needed
These aren't modules, but they do make use of these macros, so
they will need export.h to get that definition.  Previously,
they got it via the implicit module.h inclusion.

da155d5b40 sound: Add module.h to the previously silent sound users
Lots of sound drivers were getting module.h via the implicit presence
of it in <linux/device.h> but we are going to clean that up.  So
fix up those users now.

65a772172b sound: fix drivers needing module.h not moduleparam.h
The implicit presence of module.h lured several users into
incorrectly thinking that they only needed/used modparam.h
but once we clean up the module.h presence, these will show
up as build failures, so fix 'em now.

228cf79376 ALSA: intel8x0: Improve performance in virtual environment
v3: detection code is x86 and KVM specific, hide it under ifdef
v2: add detection for virtual environments (KVM and Parallels)

This patch is intended to improve performance in virtualized environments
like Parallels Desktop or KVM/VirtualBox/QEMU (virtual ICH/AC97 audio).

I/O access is very time-expensive operation in virtual world: VCPU
can be rescheduled and in the worst case we get more than 10ms delay on
each I/O access.

In the virtual environment loop exit rule
(old_civ == current_civ && old_picb == current_picb) is never satisfied,
because old_picb is never the same as current_picb due to delay inspired
by reading current_civ. As a result loop ended by timeout and we get 10x
more I/O operations.

Experimental data from Prallels Desktop 7, RHEL6 guest (I/O ops per
second):

Original code:
In Port    Counter         Callback
   f014      41550         fffff00000179d00 ac97_bm_read_civ+0x000
   f018      41387         fffff0000017a580 ac97_bm_read_picb+0x000

c09403dcc5 ALSA: hdspm - Enable all firmware ranges for PCI MADI/AES cards
From the Windows INF file, we know the firmware ranges for all RME
cards. For PCIe, a single revision ID per device (RayDAT, MADI, AIO,
AES) is used. Contrary, the older PCI versions use ranges, that is,
one revision ID per firmware version.

Instead of listing all possible revisions individually, match the range.

This commit enables all MADI and AES PCI versions ever shipped.

HDSP_VERSION_BIT has to be ORed with HDSP_S_LOAD. This fixes the detection
