      ALSA: hda: Simplify snd_hdac_refresh_widgets() · 774a075a
      Takashi Iwai authored 
      Along with the recent fix for the races of snd_hdac_refresh_widgets()
it turned out that the instantiation of widgets sysfs at
snd_hdac_sysfs_reinit() could cause a race.  The race itself was
already covered later by extending the mutex protection range, the
commit 98482377 ("ALSA: hda: Fix widget_mutex incomplete
protection"), but this also indicated that the call of *_reinit() is
basically superfluous, as the widgets shall be created sooner or later
from snd_hdac_device_register().

This patch removes the redundant call of snd_hdac_sysfs_reinit() at
first.  By this removal, the sysfs argument itself in
snd_hdac_refresh_widgets() becomes superfluous, too, because the only
case sysfs=false is always with codec->widgets=NULL.  So, we drop this
redundant argument as well.

      ALSA: line6: Fix write on zero-sized buffer · 34501219
      Takashi Iwai authored 
      LINE6 drivers allocate the buffers based on the value returned from
usb_maxpacket() calls.  The manipulated device may return zero for
this, and this results in the kmalloc() with zero size (and it may
succeed) while the other part of the driver code writes the packet
data with the fixed size -- which eventually overwrites.

This patch adds a simple sanity check for the invalid buffer size for
avoiding that problem.

      ALSA: hda: Fix widget_mutex incomplete protection · 98482377
      Evan Green authored 
      The widget_mutex was introduced to serialize callers to
hda_widget_sysfs_{re}init. However, its protection of the sysfs widget array
is incomplete. For example, it is acquired around the call to
hda_widget_sysfs_reinit(), which actually creates the new array, but isn't
still acquired when codec->num_nodes and codec->start_nid is updated. So
the lock ensures one thread sets up the new array at a time, but doesn't
ensure which thread's value will end up in codec->num_nodes. If a larger
num_nodes wins but a smaller array was set up, the next call to
refresh_widgets() will touch free memory as it iterates over codec->num_nodes
that aren't there.

The widget_lock really protects both the tree as well as codec->num_nodes,
start_nid, and end_nid, so make sure it's held across that update. It should
also be held during snd_hdac_get_sub_nodes(), so that a very old read from that
function doesn't end up clobbering a later update.

      ALSA: firewire-lib/fireworks: fix miss detection of received MIDI messages · 7fbd1753
      Takashi Sakamoto authored 
      In IEC 61883-6, 8 MIDI data streams are multiplexed into single
MIDI conformant data channel. The index of stream is calculated by
modulo 8 of the value of data block counter.

In fireworks, the value of data block counter in CIP header has a quirk
with firmware version v5.0.0, v5.7.3 and v5.8.0. This brings ALSA
IEC 61883-1/6 packet streaming engine to miss detection of MIDI
messages.

This commit fixes the miss detection to modify the value of data block
counter for the modulo calculation.

For maintainers, this bug exists since a commit 18f5ed36 ("ALSA:
fireworks/firewire-lib: add support for recent firmware quirk") in Linux
kernel v4.2. There're many changes since the commit.  This fix can be
backported to Linux kernel v4.4 or later. I tagged a base commit to the
backport for your convenience.

Besides, my work for Linux kernel v5.3 brings heavy code refactoring and
some structure members are renamed in 'sound/firewire/amdtp-stream.h'.
The content of this patch brings conflict when merging -rc tree with
this patch and the latest tree. I request maintainers to solve the
conflict to replace 'tx_first_dbc' with 'ctx_data.tx.first_dbc'.

      ALSA: hda/realtek: Add quirks for several Clevo notebook barebones · 503d90b3
      Richard Sailer authored 
      This adds 4 SND_PCI_QUIRK(...) lines for several barebone models of the ODM
Clevo. The model names are written in regex syntax to describe/match all clevo
models that are similar enough and use the same PCI SSID that this fixup works
for them.

Additionally the lines regarding SSID 0x96e1 and 0x97e1 didn't fix audio for the
all our Clevo notebooks using these SSIDs (models Clevo P960* and P970*) since
ALC1220_FIXP_CLEVO_PB51ED_PINS swapped pins that are not necesarry to be
swapped. This patch initiates ALC1220_FIXUP_CLEVO_P950 instead for these model
and fixes the audio.

ASoC: Fixes for v5.2

There's an awful lot of fixes here, almost all for the newly introduced
SoF DSP drivers (including a few things it turned up in shared code).
This is a large and complex piece of code so it's not surprising that
there have been quite a few issues here, fortunately things seem to have
mostly calmed down now.  Otherwise there's just a smattering of small fixes.

      ASoC: Intel: sst: fix kmalloc call with wrong flags · 3da428ff
      Alex Levin authored 
      When calling kmalloc with GFP_KERNEL in case CONFIG_SLOB is unset,
kmem_cache_alloc_trace is called.

In case CONFIG_TRACING is set, kmem_cache_alloc_trace will ball
slab_alloc, which will call slab_pre_alloc_hook which might_sleep_if.

The context in which it is called in this case, the
intel_sst_interrupt_mrfld, calling a sleeping kmalloc generates a BUG():

      ASoC: sun4i-codec: fix first delay on Speaker · 1f2675f6
      Georgii Staroselskii authored 
      Allwinner DAC seems to have a delay in the Speaker audio routing. When
playing a sound for the first time, the sound gets chopped. On a second
play the sound is played correctly. After some time (~5s) the issue gets
back.

This commit seems to be fixing the same issue as bf14da7e but
for another codepath.

This is the DTS that was used to debug the problem.

&codec {
        allwinner,pa-gpios = <&r_pio 0 11 GPIO_ACTIVE_HIGH>; /* PL11 */
        allwinner,audio-routing =
                "Speaker", "LINEOUT";

        status = "okay";

      We met another Acer Aspire laptop which has the problem on the
headset-mic, the Pin 0x19 is not set the corret configuration for a
mic and the pin presence can't be detected too after plugging a
headset. Kailang suggested that we should set the coeff to enable the
mic and apply the ALC269_FIXUP_LIFEBOOK_EXTMIC. After doing that,
both headset-mic presence and headset-mic work well.

The existing ALC255_FIXUP_ACER_MIC_NO_PRESENCE set the headset-mic
jack to be a phantom jack. Now since the jack can support presence
unsol event, let us imporve it to set the jack to be a normal jack.
