Since there are a few corner cases where the S/G buffer allocation
isn't performed (e.g. depending on IOMMU implementations), it'd be
better to allow the default buffer preallocation size for x86, too.
The default for x86 is still kept to 0, as it should work in most
cases.

The cs35l34 adds a useless rate constraint on startup.
It does not set SNDRV_PCM_RATE_KNOT and the rates set are already a subset
of the ones provided in the constraint list, so it is a no-op.
>From the rest of the code, it is likely HW supports more than the 32, 44.1
and 48kHz listed in CS35L34_RATES but there is no way to know for sure
without proper documentation.
Keep the driver as it is for now and just drop the useless constraint.

This adds a sample rate definition for 12kHz, 24kHz and 128kHz.
Admittedly, just a few drivers are currently using these sample
rates but there is enough of a recurrence to justify adding a definition
for them and remove some custom rate constraint code while at it.
The new definitions are not added to the interval definitions, such as
SNDRV_PCM_RATE_8000_44100, because it would silently add new supported
rates to drivers that may or may not support them. For sure the drivers
have not been tested for these new rates so it is better to leave them out
of interval definitions.
That being said, the added rates are multiples of well know rates families,
it is very likely that a lot of devices out there actually supports them.

Implement sync, output format, and input status mixer controls, to allow
the interface to be used as a straight ADAT/SPDIF (+ Headphones) I/O
interface.
This does not implement the matrix mixer, output gain controls, or input
level meter feedback. The full mixer interface is only really usable
using a dedicated userspace control app (there are too many mixer nodes
for alsamixer to be usable), so for now we leave it up to userspace to
directly control these features using raw USB control messages. This is
similar to how it's done with some FireWire interfaces (ffado-mixer).

We used to wrap with no_free_ptr() for the return value from
memdup_user() with errors where the auto cleanup is applied. This was
a workaround because the initial implementation of kfree auto-cleanup
checked only NULL pointers.
Since recently, though, the kfree auto-cleanup checks with
IS_ERR_OR_NULL() (by the commit cd7eb8f83fcf ("mm/slab: make
__free(kfree) accept error pointers")), hence those workarounds became
superfluous. Let's drop them now.

We do not need model specific HDA quirks to construct the component
binding details of Cirrus Logic companion amplifiers as this information
is already present in the ACPI.
Quirks are then only required for special workarounds not described in
the ACPI such as internal configuration of the Realtek codecs.
The codec pointer is now initialized in hda_component_manager_init() so
that we can detect when companion amplifiers are found in the ACPI but
the SSID invokes a quirk that also attempts to create the component
binding.

The dw-hdmi drm bridge driver is the only one who still uses the ALSA

buffer management wasn't taken for this legacy stuff, as we had little

Instead, this patch moves the vmalloc buffer stuff into the dw-hdmi
driver code itself, so that we can drop them from ALSA core code
afterwards.
There should be no functional changes.

Move the initialization of parent->mutex into
hda_component_manager_init() so that it is always valid.
In hda_component_manager_bind() do not clear the parent information.
Only zero-fill the per-component data ready for it to be filled in
by the components as they bind.
Previously parent->mutex was being initialized only in
hda_component_manager_bind(). This meant that it was only
initialized if all components appeared and there was a bind callback.
If there wasn't a bind the mutex object was not valid when the

The existing CS35L56 products can make use of the fixup function that
works out the component binding details so we can remove the fixed
configuration fixup functions.

All callers of get_event_dest_clienter() pass 0 to the filter
argument, and it means that the check there is utterly redundant.
Drop the superfluous filter argument and its check as a code cleanup.

UMP events don't use the event type field, hence it's invalid to apply
the filter, which may drop the events unexpectedly.
Skip the event filtering for UMP events, instead.

fuse_notify_store(), unlike fuse_do_readpage(), does not enable page
zeroing (because it can be used to change partial page contents).
So fuse_notify_store() must be more careful to fully initialize page
contents (including parts of the page that are beyond end-of-file)
before marking the page uptodate.
The current code can leave beyond-EOF page contents uninitialized, which
makes these uninitialized page contents visible to userspace via mmap().
This is an information leak, but only affects systems which do not
enable init-on-alloc (via CONFIG_INIT_ON_ALLOC_DEFAULT_ON=y or the
corresponding kernel command line parameter).

Add a test for the new functionality of userspace-driven timers and the
tool which allows us to count timer ticks in a certain time period. The
test:
1. Creates a userspace-driven timer with ioctl to /dev/snd/timer
2. Starts the `global-timer` application to count the ticks of the timer
from step 1.
3. Asynchronously triggers the timer multiple times with some interval
4. Compares the amount of caught ticks with the amount of trigger calls.
Since we can't include <alsa/asoundlib.h> and <sound/asound.h> in one
file due to overlapping declarations, I have to split the test into two
applications: one of them counts the amount of timer ticks in the
defined time period, and another one is the actual test which creates
the timer, triggers it periodically and starts the first app to count
the amount of ticks in a separate thread.
Besides from testing the functionality itself, the test represents a
sample application showing userspace-driven ALSA timers API.
Also, the timer test includes a test case which tries to create a timer
with invalid resolution (=0), and NULL as a timer info structure.

Implement two ioctl calls in order to support virtual userspace-driven
ALSA timers.
The first ioctl is SNDRV_TIMER_IOCTL_CREATE, which gets the
snd_timer_uinfo struct as a parameter and puts a file descriptor of a
virtual timer into the `fd` field of the snd_timer_unfo structure. It
also updates the `id` field of the snd_timer_uinfo struct, which
provides a unique identifier for the timer (basically, the subdevice
number which can be used when creating timer instances).
This patch also introduces a tiny id allocator for the userspace-driven
timers, which guarantees that we don't have more than 128 of them in the
system.
Another ioctl is SNDRV_TIMER_IOCTL_TRIGGER, which allows us to trigger
the virtual timer (and calls snd_timer_interrupt for the timer under
the hood), causing all of the timer instances binded to this timer to
execute their callbacks.
The maximum amount of ticks available for the timer is 1 for the sake of
simplicity of the userspace API. 'start', 'stop', 'open' and 'close'
callbacks for the userspace-driven timers are empty since we don't
really do any hardware initialization here.
