Intel HDMI LPE audio driver has its own mmap callback that mimics with
the noncached page attributes, but this is rather superfluous and can
be replaced with the standard helper, as the device is only for
playback and the write-cache should suffice.
This patch drops the own code and just uses the standard helper.

New device id for Corsair Virtuoso SE RGB Wireless that currently is not
in the mixer_map. This entry in the mixer_map is necessary in order to
label its mixer appropriately and allow userspace to pick the correct
volume controls. For instance, my own Corsair Virtuoso SE RGB Wireless
headset has this new ID and consequently, the sidetone and volume are not
working correctly without this change.

This commit fixes the bug. The bug has no disadvantage for the non-
control/notify AV/C transactions since the flag has an effect for AV/C
response with INTERIM (0x0f) status which is not used for the transactions
in AV/C general specification.

The variable bytes is being assigned a value that is never read, it
is being re-assigned inside a following if block. The assignment is
redundant and can be removed.

This patch fix the second dai driver's dai widget can't connect to the
endpoint. Because "bt-sco-pcm" and "bt-sco-pcm-wb" dai driver have the
same stream_name, so it will cause they have the same widget name.
Therefor it will just create only one route when do snd_soc_dapm_add_route
that only find the widget through the widget name.

pcm name can be "Analog" and "Alt Analog", cpcm->name can be
"Analog Codec DAI" and "Alt Analog Codec DAI". When pcm_name
is "Analog", "Analog Codec DAI" and "Alt Analog Codec DAI" are
both satisfy the 'if (strstr(cpcm->name, pcm_name))' condition,
which may cause the returned cpcm to be "Alt Analog Codec DAI".
Even if we get the pcm name by id, and "Analog Codec DAI" goes
into the loop before "Alt Analog Codec DAI", but I still think
we'd better have multiple insurances against unexpected return
values. After, we can correctly return the expected result
even if other relevant places are changed.

Merge series from Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>:
Two cleanups to remove an unused filename and typos, and one addition
of an ACPI matching table for a Dell SoundWire SKU without local
microphones.
The main change is the addition of a common 'sof-ssp-amp' machine
driver for devices with amplifiers only (no headset codec) and
different connections using I2S links (Bluetooth offload, HDMI
receiver). It's likely that the amplifier will be swapped out by OEMs,
this machine driver provides a relatively generic solution to avoid
copy-paste of similar solutions.
The copy_to/from_user() functions return the number of bytes remaining
to be copied. This function needs to return negative error codes
because snd_soc_pcm_component_copy_user() treats positive returns as
success in soc_component_ret().

There is one call trace that snd_soc_register_card()
->snd_soc_bind_card()->soc_init_pcm_runtime()
->snd_soc_dai_compress_new()->snd_soc_new_compress().
In the trace the 'codec_dai' transfers from card->dai_link,
and we can see from the snd_soc_add_pcm_runtime() in
snd_soc_bind_card() that, if value of card->dai_link->num_codecs
is 0, then 'codec_dai' could be null pointer caused
by index out of bound in 'asoc_rtd_to_codec(rtd, 0)'.
And snd_soc_register_card() is called by various platforms.
Therefore, it is better to add the check in the case of misusing.
And because 'cpu_dai' has already checked in soc_init_pcm_runtime(),
there is no need to check again.
Adding the check as follow, then if 'codec_dai' is null,
snd_soc_new_compress() will not pass through the check
'if (playback + capture != 1)', avoiding the leftover use of
'codec_dai'.

In dmaengine_pcm_set_runtime_hwparams() period_bytes_min is hardcoded to
256. For some applications that may be too big. This patch changes that
to calculate the value based on dma_data->maxburst. The correct value
would be maxburst multiplied by the address width of the hardware FIFO.
Unfortunately the address width is dynamically calculated based on the
stream parameters and is not known at open time, so the worst case
is chosen here which is 8 bytes, the maximum that is supported by
dmaengine drivers.
Not all drivers may set a maxburst value, so we fall back to the
previously used hardcoded value of 256 bytes.

Initializing the static variable to 0 causes the following error
when exec checkpatch:
ERROR: do not initialise statics to 0
FILE: sound/sound_core.c:142:
static int preclaim_oss = 0;
In addition, considering the following way of writing
139: #ifdef config_sound_oss_core_preclaim
140: Static int preclaim_oss = 1;
141: #ELSE
142: Static int preclaim_oss = 0;
143: #ENDIF
We can optimize it by IS_ENABLED(CONFIG_SOUND_OSS_CORE_PRECLAIM),
so modified it to
static int preclaim_oss = IS_ENABLED(CONFIG_SOUND_OSS_CORE_PRECLAIM);

platform_get_resource(pdev, IORESOURCE_IRQ, ..) relies on static
allocation of IRQ resources in DT core code, this causes an issue
when using hierarchical interrupt domains using "interrupts" property
in the node as this bypassed the hierarchical setup and messed up the
irq chaining.
In preparation for removal of static setup of IRQ resource from DT core
code use platform_get_irq().
