ALSA: hda/realtek - PCI quirk for Medion E4254
The laptop has a combined jack to attach headsets on the right.
The BIOS encodes them as two different colored jacks at the front,
but otherwise it seems to be configured ok. But any adaption of
the pins config on its own doesn't fix the jack detection to work
in Linux. Still Windows works correct.
This is somehow fixed by chaining ALC256_FIXUP_ASUS_HEADSET_MODE,
which seems to register the microphone jack as a headset part and
also results in fixing jack sensing, visible in dmesg as:
-snd_hda_codec_realtek hdaudioC0D0: Mic=0x19
+snd_hda_codec_realtek hdaudioC0D0: Headset Mic=0x19
[ Actually the essential change is the location of the jack; the
driver created "Front Mic Jack" without the matching volume / mute
control element due to its jack location, which confused PA.

ALSA: dice: fix wrong packet parameter for Alesis iO26
At higher sampling rate (e.g. 192.0 kHz), Alesis iO26 transfers 4 data
channels per data block in CIP.
Both iO14 and iO26 have the same contents in their configuration ROM.
For this reason, ALSA Dice driver attempts to distinguish them according
to the value of TX0_AUDIO register at probe callback. Although the way is
valid at lower and middle sampling rate, it's lastly invalid at higher
sampling rate because because the two models returns the same value for
read transaction to the register.
In the most cases, users just plug-in the device and ALSA dice driver
detects it. In the case, the device runs at lower sampling rate and
the driver detects expectedly. For this reason, this commit leaves the
way to detect as is.

2 bytes in MSB of register for clock status is zero during intermediate
state after changing status of sampling clock in models of TASCAM FireWire
series. The duration of this state differs depending on cases. During the
state, it's better to retry reading the register for current status of
the clock.
In current implementation, the intermediate state is checked only when
getting current sampling transmission frequency, then retry reading.
This care is required for the other operations to read the register.

It is easy to create bug at the such code, and it will be difficult to

SoC: simple-card-utils: set 0Hz to sysclk when shutdown
This patch set 0Hz to sysclk when shutdown the card.
Some codecs set rate constraints that derives from sysclk. This
mechanism works correctly if machine drivers give fixed frequency.
But simple-audio and audio-graph card set variable clock rate if
'mclk-fs' property exists. In this case, rate constraints will go
bad scenario. For example a codec accepts three limited rates
(mclk / 256, mclk / 384, mclk / 512).
Bad scenario as follows (mclk-fs = 256):
- Initialize sysclk by correct value (Ex. 12.288MHz)
- Codec set constraints of PCM rate by sysclk
48kHz (1/256), 32kHz (1/384), 24kHz (1/512)
- Play 48kHz sound, it's acceptable
- Sysclk is not changed
- Play 32kHz sound, it's acceptable
- Set sysclk to 8.192MHz (= fs * mclk-fs = 32k * 256)
- Codec set constraints of PCM rate by sysclk
32kHz (1/256), 21.33kHz (1/384), 16kHz (1/512)
- Play 48kHz again, but it's NOT acceptable because constraints
do not allow 48kHz
So codecs treat 0Hz sysclk as signal of applying no constraints to
avoid this problem.

ASoC: ams-delta: Take control over audio mute GPIO pins
Since commit
1137ceee76ba ("ARM: OMAP1: ams-delta: Don't request unused
GPIOs"), on-board audio has appeared muted. It has been discovered that
believed to be unused GPIO pins "hookflash1" and "hookflash2" need to be
set low for audible sound in handsfree and handset mode respectively.
According to Amstrad E3 wiki, the purpose of both pins hasn't been
clearly identified. Original Amstrad software used to produce a high
pulse on them when the phone was taken off hook or recall was pressed.
With the current findings, we can assume the pins provide a kind of
audio mute function, separately for handset and handsfree operation
modes.
Commit
2afdb4c41d78 ("ARM: OMAP1: ams-delta: Fix audio permanently
muted") attempted to fix the issue temporarily by hogging the GPIO pin
"hookflash1" renamed to "audio_mute", however the fix occurred
incomplete as it restored audible sound only for handsfree mode.
Stop hogging that pin, rename the pins to "handsfree_mute" and
"handset_mute" respectively and implement appropriate DAPM event
callbacks for "Speaker" and "Earpiece" DAPM widgets.

This reverts commit
558682b5291937a70748d36fd9ba757fb25b99ae.
Chris Wilson reports that it breaks his CPU hotplug test scripts. In
particular, it breaks offlining and then re-onlining the boot CPU, which
we treat specially (and the BIOS does too).
The symptoms are that we can offline the CPU, but it then does not come
back online again:
smpboot: CPU 0 is now offline
smpboot: Booting Node 0 Processor 0 APIC 0x0
smpboot: do_boot_cpu failed(-1) to wakeup CPU#0
Thomas says he knows why it's broken (my personal suspicion: our magic
handling of the "cpu0_logical_apicid" thing), but for 5.3 the right fix
is to just revert it, since we've never touched the LDR bits before, and
it's not worth the risk to do anything else at this stage.
[ Hotpluging of the boot CPU is special anyway, and should be off by
default. See the "BOOTPARAM_HOTPLUG_CPU0" config option and the
cpu0_hotplug kernel parameter.
In general you should not do it, and it has various known limitations
(hibernate and suspend require the boot CPU, for example).
But it should work, even if the boot CPU is special and needs careful
treatment - Linus ]

ALSA: firewire-tascam: add note for FE-8
TASCAM FE-8 is the rest of model in TASCAM FireWire series. This device
has no functionality to process audio signal and MIDI messages. Instead,
it transfers control messages to host system corresponding to operations
for some faders, buttons and knobs on its surface.
Unlike the other devices in this series, the control messages are
transmitted by asynchronous transactions. Some registers of device are
used for registration of destination address for the transaction. The
transaction includes quadlet-aligned data up to 32 quadlets.
Userspace applications can receive the transaction and parse it for
control message via Linux FireWire subsystem, without any support by
ALSA firewire-tascam driver. Therefore the driver gives no support
for it.
This commit removes placeholder for FE-8 and add some comment for its
functionalities as notes.

Add Acer Aspire Ethos 8951G model quirk
This notebook has 6 built in speakers for 5.1 surround support, however
only two got autodetected and have also not been assigned correctly.
This patch enables all speakers and also fixes muting when headphones are
plugged in.
The speaker layout is as follows:
pin 0x15 Front Left / Front Right
pin 0x18 Front Center / Subwoofer
pin 0x1b Rear Left / Rear Right (Surround)
The quirk will be enabled automatically on this hardware, but can also be
activated manually via the model=aspire-ethos module parameter.
Caveat: pin 0x1b is shared between headphones jack and surround speakers.
When headphones are plugged in, the surround speakers get muted
automatically by the hardware, however all other speakers remain
unmuted. Currently it's not possible to make use of the generic automute
function in the driver, because such shared pins are not supported.
If we would change the pin settings to identify the pin as headphones,
the surround channel and thus the ability to select 5.1 profiles would
get lost.
This quirk solves the above problem by monitoring jack state of 0x1b and
by connecting/disconnecting all remaining speaker pins when something
gets plugged in or unplugged from the headphones jack port.

iommu/amd: Flush old domains in kdump kernel
When devices are attached to the amd_iommu in a kdump kernel, the old device
table entries (DTEs), which were copied from the crashed kernel, will be
overwritten with a new domain number. When the new DTE is written, the IOMMU
is told to flush the DTE from its internal cache--but it is not told to flush
the translation cache entries for the old domain number.
Without this patch, AMD systems using the tg3 network driver fail when kdump
tries to save the vmcore to a network system, showing network timeouts and
(sometimes) IOMMU errors in the kernel log.
This patch will flush IOMMU translation cache entries for the old domain when
a DTE gets overwritten with a new domain number.

drm/vmwgfx: Fix double free in vmw_recv_msg()
We recently added a kfree() after the end of the loop:
if (retries == RETRIES) {
kfree(reply);
return -EINVAL;
}
There are two problems. First the test is wrong and because retries
equals RETRIES if we succeed on the last iteration through the loop.
Second if we fail on the last iteration through the loop then the kfree
is a double free.
When you're reading this code, please note the break statement at the
end of the while loop. This patch changes the loop so that if it's not
successful then "reply" is NULL and we can test for that afterward.

configfs: provide exclusion between IO and removals
Make sure that attribute methods are not called after the item
has been removed from the tree. To do so, we
* at the point of no return in removals, grab ->frag_sem
exclusive and mark the fragment dead.
* call the methods of attributes with ->frag_sem taken
shared and only after having verified that the fragment is still
alive.
The main benefit is for method instances - they are
guaranteed that the objects they are accessing *and* all ancestors
are still there. Another win is that we don't need to bother
with extra refcount on config_item when opening a file -
the item will be alive for as long as it stays in the tree, and
we won't touch it/attributes/any associated data after it's
been removed from the tree.
