commit 225db5762dc1a35b26850477ffa06e5cd0097243 upstream.

When OSS emulation is loaded on ISA SB AWE32 chip, we get now kernel
warnings like:
  WARNING: CPU: 0 PID: 2791 at fs/sysfs/dir.c:31 sysfs_warn_dup+0x51/0x80()
  sysfs: cannot create duplicate filename '/devices/isa/sbawe.0/sound/card0/seq-oss-0-0'

It's because both emux synth and opl3 drivers try to register their
OSS device object with the same static index number 0.  This hasn't
been a big problem until the recent rewrite of device management code
(that exposes sysfs at the same time), but it's been an obvious bug.

This patch works around it just by using a different index number of
emux synth object.  There can be a more elegant way to fix, but it's
enough for now, as this code won't be touched so often, in anyway.

<title>ASoC: fix broken pxa SoC support</title>

commit 3c8f7710c1c44fb650bc29b6ef78ed8b60cfaa28 upstream.

The previous fix of pxa library support, which was introduced to fix the
library dependency, broke the previous SoC behavior, where a machine
code binding pxa2xx-ac97 with a coded relied on :
 - sound/soc/pxa/pxa2xx-ac97.c
 - sound/soc/codecs/XXX.c

For example, the mioa701_wm9713.c machine code is currently broken. The
"select ARM" statement wrongly selects the soc/arm/pxa2xx-ac97 for
compilation, as per an unfortunate fate SND_PXA2XX_AC97 is both declared
in sound/arm/Kconfig and sound/soc/pxa/Kconfig.

Fix this by ensuring that SND_PXA2XX_SOC correctly triggers the correct
pxa2xx-ac97 compilation.

<title>ALSA: usb-audio: Add a more accurate volume quirk for AudioQuest DragonFly</title>

<id>d359d1d221bc77b3a45719c8f010b604f39c58c4</id>
<content type='text'>
commit 42e3121d90f42e57f6dbd6083dff2f57b3ec7daa upstream.

AudioQuest DragonFly DAC reports a volume control range of 0..50
(0x0000..0x0032) which in USB Audio means a range of 0 .. 0.2dB, which
is obviously incorrect and would cause software using the dB information
in e.g. volume sliders to have a massive volume difference in 100..102%
range.

Commit 2d1cb7f658fb ("ALSA: usb-audio: add dB range mapping for some
devices") added a dB range mapping for it with range 0..50 dB.

However, the actual volume mapping seems to be neither linear volume nor
linear dB scale, but instead quite close to the cubic mapping e.g.
alsamixer uses, with a range of approx. -53...0 dB.

Replace the previous quirk with a custom dB mapping based on some basic
output measurements, using a 10-item range TLV (which will still fit in
alsa-lib MAX_TLV_RANGE_SIZE).

Tested on AudioQuest DragonFly HW v1.2. The quirk is only applied if the
range is 0..50, so if this gets fixed/changed in later HW revisions it
will no longer be applied.

v2: incorporated Takashi Iwai's suggestion for the quirk application
method

commit 0689a86ae814f39af94a9736a0a5426dd82eb107 upstream.

The Steinberg MI2 and MI4 interfaces are compatible with the USB class
audio spec, but the MIDI part of the devices is reported as a vendor
specific interface.

This patch adds entries to quirks-table.h to recognize the MIDI
endpoints. Audio functionality was already working and is unaffected by
this change.

commit ebb6ad73e645b8f2d098dd3c41d2ff0da4146a02 upstream.

VMID Control 0 BIT[2:1] is VMID Divider Enable and Select

00 = VMID disabled (for OFF mode)
01 = 2 x 50kΩ divider (for normal operation)
10 = 2 x 250kΩ divider (for low power standby)
11 = 2 x 5kΩ divider (for fast start-up)

So WM8903_VMID_RES_250K should be 2 &lt;&lt; 1, which is 4.
