596ae97ab0 ALSA: oxygen: Allocate resources with device-managed APIs
This patch converts the resource management in PCI oxygen drivers with
devres as a clean up.  Each manual resource management is converted
with the corresponding devres helper, and the page allocations are
done with the devres helper.

This should give no user-visible functional changes.

c19935f047 ALSA: nm256: Allocate resources with device-managed APIs
This patch converts the resource management in PCI nm256 driver with
devres as a clean up.  Each manual resource management is converted
with the corresponding devres helper, and the card object release is
managed now via card->private_free instead of a lowlevel snd_device.

This should give no user-visible functional changes.

3fcaf24e5d ALSA: hda: Allocate resources with device-managed APIs
This patch is an attempt to slightly simplify the resource management
in HD-audio code, by using some device-managed APIs.  Only a few
resources like PCI enablement and PCI resources managed via devres,
but most of the rest code dealing with HD-audio core stuff couldn't be
changed so much, hence the changes in this patch are pretty small in
the end.  A special caveat is needed for the card object: we can't
move the card object release into devres, because the driver is
involved with the component stuff and its unregistiration doesn't work
well from devres release at all.

86bde74dbf ALSA: atiixp: Allocate resources with device-managed APIs
Like the previous patch, this patch converts the resource allocations
with device-managed API calls, so that we can reduce resource-free
calls.

The atiixp drivers are simpler than intel8x0, and even the irq can be
allocated with devres.

The end result is a good amount of code reduction.

7835e0901e ALSA: intel8x0: Allocate resources with device-managed APIs
This patch refactors the intel8x0 and intel8x0m driver codes using
devres and gets rid of the driver remove callback.

The conversion is fairly straightforward: each API call is replaced
with the device-managed API function, e.g. pci_enable_device() ->
pcim_enable_device(), and so on.  The buffer descriptor list is
allocated with a new API, snd_devm_alloc_pages().

A slight code structure change is that the intel8x0 object is
allocated as a card's private_data instead of the own lowlevel
snd_device object.  This simplifies the resource management.
And, the take-down procedure is triggered via card->private_free, and
it's registered at the end of the whole initialization, i.e. after the
all resources get properly managed.

The only not-devres-managed resource is the irq handler.  Since we
need to release at suspend and re-acquire at resume (otherwise
something weird happens on some machines), this is still managed
manually.  But the rest are all freed automatically.

The end result is a good amount of code reduction.

c2b94954ad ALSA: core: Add device-managed request_dma()
This patch adds a devres-supported helper for requesting an ISA DMA
channel that will be automatically freed at the device unbinding.
It'll be used by quite a few ISA sound drivers.

e8ad415b7a ALSA: core: Add managed card creation
As a second step for preliminary to widen the devres usages among
sound drivers, this patch adds a new ALSA core API function,
snd_devm_card_new(), to create a snd_card object via devres.
When a card object is created by this new function, snd_card_free() is
called automatically and the card object resource gets released at the
device unbinding time.

However, the story isn't that simple.  A caveat is that we have to
call snd_card_free() at the very first of the whole resource release
procedure, in order to assure that the all exposed devices on
user-space are deleted and sync with processes accessing those devices
before releasing resources.

For achieving it, snd_card_register() adds a new devres action to
trigger snd_card_free() automatically when the given card object is a
"managed" one.  Since usually snd_card_register() is the last step of
the initialization, this should work in most cases.

With all these tricks, some drivers can get rid of the whole driver
remove callback code.

About a bit of implementation details: the patch adds two new flags to
snd_card object: managed and releasing.  The former indicates that the
object was created via snd_devm_card_new(), and the latter is used for
avoiding the double-free of snd_card_free() calls.  Both flags are
fairly internal and likely uninteresting to normal users.

427ae2689d ALSA: core: Add device-managed page allocator helper
This is a preparation for allowing devres usages more widely in
various sound drivers.  As a first step, this patch adds a new
allocator function, snd_devm_alloc_pages(), to manage the allocated
pages via devres, so that the pages will be automagically released as
device unbinding.

Unlike the old snd_dma_alloc_pages(), the new function returns
directly the snd_dma_buffer pointer.  The caller needs NULL-check for
the allocation error appropriately.

Also, since a real device pointer is mandatory for devres,
SNDRV_DMA_TYPE_CONTINUOUS or SNDRV_DMA_TYPE_VMALLOC type can't be used
for this function.

2c4e315457 ALSA: compress: Initialize mutex in snd_compress_new()
Currently the snd_compr.lock mutex isn't initialized in the API
functions although the lock is used many places in other code in
compress offload API.  It's because the object was expected to be
initialized via snd_compress_register(), but this was never used by
ASoC, which is the only user.  Instead, ASoC initializes the mutex by
itself, and this is error-prone.

This patch moves the mutex initialization into the more appropriate
place, snd_compress_new(), for avoiding the missing init.

27757876d1 ALSA: intel8x0: Skip ac97 clock measurement on VM
The intel8x0 driver tries to measure the AC97 bus clock at the probe
time because there have been machines that are driven in different
rate (44.1kHz vs 48kHz).  This was the past and currently most of
usages of this driver are on VM, and those are certainly fixed with
48k clock, hence it's useless and waste of time to measure.

This patch is an optimization, setting the fixed 48k rate if it's
detected to be running on a VM.

4ff1922948 ALSA: hda/hdmi: Add option to enable all pins forcibly
On Intel platforms, we always enable all pins no matter what BIOS
sets, but for others, we still take the conservative approach, and the
HD-audio HDMI codec driver enables the streams only for the pins that
are enabled by BIOS, and skips the disabled pins.  This seems not good
for some machines that have (as expected) broken BIOS, resulting in
the lack of needed outputs.

There is an allow-list in the driver code to enable all pins, but its
addition needs a recompilation.  This patch adds a module option for
user's convenience to enable all pins forcibly on the fly.  User can
pass snd_hda_codec_hdmi.enable_all_pins=1 option for testing, and once
confirmed, we may add a static entry in force_connect_list[].
