Embedding the ctl_dev in the snd_card object may result in UAF when
the delayed kobj release is used; at the delayed kobj release, it
still accesses the struct device itself while the card memory (that
embeds the struct device) may be already gone.
As a workaround, detach the struct device from the card object by
allocating via the new snd_device_alloc() helper. The rest are just
replacing ctl_dev access to the pointer.
This is based on the fix Curtis posted initially. In this patch, the
changes are split and use the new helper function instead.

`strncpy` is deprecated for use on NUL-terminated destination strings [1].
A suitable replacement is `strscpy` [2] due to the fact that it
guarantees NUL-termination on its destination buffer argument which is
_not_ the case for `strncpy`!
It should be noted that the current implementation is unlikely to have a
bug because `drv_name` is a string literal with a size of 9 while
`card->driver` has a size of 16. However, it is probably worthwhile to
switch to a more robust and less ambiguous interface.

A RAM firmware can only be downloaded if the CS35L56 is currently
running from ROM firmware. The driver must not try to overwrite
the RAM if the CS35L56 is already running from that RAM.
Firmware can be downloaded in these two cases:
- The BIOS has already patched the firmware (secured mode).
In this case the firmware files will only contain tunings that
are safe to overwrite.
- The CS35L56 is running the built-in ROM firmware.
After a RAM firmware has been downloaded it can only be cleared by
hard resetting CS35L56. Some systems only hard-reset during
power-on and do not give the driver control of hard reset.

strscpy, strscpy_pad, strtomem and strtomem_pad (amongst others).
Technically, my patch yields subtly different behavior. The original
implementation with `strncpy` would fill the entire destination buffer
with null bytes [3] while `strscpy` will leave the junk, uninitialized
bytes trailing after the _mandatory_ NUL-termination. So, if somehow
`card->driver` or `card->shortname` require this NUL-padding behavior
then `strscpy_pad` should be used. My interpretation, though, is that
the aforementioned fields are just fine as NUL-terminated strings.
Please correct my assumptions if needed and I'll send in a v2.

- Create a library function for intlog10() and use it in the NAU8825

- Include the ASoC tests, including the topology tests, in the default

- Support for AMD machines with MAX98388 and NAU8821, Cirrus Logic

Merge series from Richard Fitzgerald <rf@opensource.cirrus.com>:
This set of patches adds support for using the CS35L56 boosted smart
amplifier on HDA systems. In these systems the CS35L56 audio is
routed through a HDA-to-I2S bridge codec.
This doesn't include the changes to the Realtek driver to actually hook
up the CS35L56 driver, because we don't yet have the QUIRK IDs to
associate it with. But we want to publish the driver now so that it is
available for bringing up hardware with the CS35L56.
The first 9 patches are moving code out of the ASoC driver and into the
shared library so that it can be shared with the HDA driver.
Patch #10 fixes missing #includes in the HDA headers so that the CS35L56
driver doesn't have to #include headers that it doesn't use.
Currently we only mute after playback has finished, and unmute
prior to setting global enable. To prevent any possible pops
and clicks, mute at probe, and then only unmute after global
enable is set.

To ensure consistency between the HDA core and the CS35L41 HDA
driver, add a device_link between them. This ensures that the
HDA core will suspend first, and resume second, meaning the
amp driver will not miss any events from the playback hook from
the HDA core during system suspend and resume.

In order to correctly pause audio on suspend, amps using external boost
require parts of the pause sequence to be called for all amps before moving
on to the next steps.
For example, as part of pausing the audio, the VSPK GPIO must be disabled,
but since this GPIO is controlled by one amp, but controls the boost for
all amps, it is required to separate the calls.
During playback this is achieved by using the pre and post playback hooks,
however during system suspend, this is not possible, so to separate the
calls, we use both the .prepare and .suspend calls to pause the audio.
Currently, for this reason, we do not restart audio on system resume.
However, we can support this by relying on the playback hook to resume
playback after system suspend.

Use new hooks to ensure separation between play/pause actions,
as required by external boost.
External Boost on CS35L41 requires the amp to go through a
particular sequence of steps. One of these steps involes
the setting of a GPIO. This GPIO is connected to one or
more of the amps, and it may control the boost for all of
the amps. To ensure that the GPIO is set when it is safe
to do so, and to ensure that boost is ready for the rest of
the sequence to be able to continue, we must ensure that
the each part of the sequence is executed for each amp
before moving on to the next part of the sequence.
Some of the Play and Pause actions have moved from Open to
Prepare. This is because Open is not guaranteed to be called
again on system resume, whereas Prepare should.

These hooks can be used to add callbacks that would be run before and after
the main playback hooks. These hooks would be called for all amps, before
moving on to the next hook, i.e. pre_playback_hook would be called for
all amps, before the playback_hook is called for all amps, then finally
the post_playback_hook is called for all amps.

In order to properly system suspend, it is necessary to unload the firmware
and ensure the chip is ready for shutdown (if necessary). If the system
is currently in runtime suspend, it is necessary to wake up the device,
and then make it ready. Currently, the wake does not correctly resync
the device, which may mean it cannot suspend correctly. Fix this by
performaing a resync.

To enable the speaker output in external boost mode, 2 registers must
be set, one after another. The longer the time between the writes of
the two registers, the more likely, and more loudly a pop may occur.
To minimize this, an mbox command can be used to allow the firmware
to perform this action, minimizing any delay between write, thus
minimizing any pop or click as a result. The old method will remain
when running without firmware.

The LPASS macro drivers all acquire a number of clocks, but give no
indication when clk_get() fails, making it hard to identify and debug
system configuration issues. Make these drivers provide useful debug
information when this happens.

Add a driver for the Cirrus Logic CS35L56 amplifier. This uses the same
component binding API as the CS35L41 driver. This is not a standalone
HDA device; it provides control of the CS35L56 for systems that use a
combination of an HDA codec and CS35L56 amplifiers with audio routed
through the HDA codec.
The CS35L56 combines a high-performance mono audio amplifier, Class-H
tracking inductive boost converter, Halo Core(TM) DSP and a DC-DC boost
converter supporting Class-H tracking.
Control interfaces are I2C or SPI through the standard Linux I2C or SPI
bus framework.
Most chip functionality is controlled by on-board ROM firmware that is
always running. Firmware patches can be applied by the driver in the form
of a .wmfw file (firmware patch) and/or a .bin file (system tuning).

Add #includes of dependencies into hda_auto_parser.h and hda_generic.h
hda_auto_parser.h uses definitions in hda_local.h.
hda_generic.h uses definitions in hda_local.h and hda_auto_parser.h.
It also references struct hda_jack_callback, but only as a pointer.
This has been forward-declared so hda_jack.h only needs to be
included in source that actually uses it.

Move issuing of a CS35L56_MBOX_CMD_SHUTDOWN command and then waiting for
the DSP to reach CS35L56_HALO_STATE_SHUTDOWN in the register appropriate
for the hardware revision into a common function.
