These drivers don't use the driver_data member of struct i2c_device_id,
so don't explicitly initialize this member.
This prepares putting driver_data in an anonymous union which requires
either no initialization or named designators. But it's also a nice
cleanup on its own.

The codec leaves tie combo jack's sleeve/ring2 to floating status

Merge series from Cezary Rojewski <cezary.rojewski@intel.com>:
The avs-driver continues to be utilized on more recent Intel machines.
As TGL-based (cAVS 2.5) e.g.: RPL, inherit most of the functionality
from previous platforms:
SKL <- APL <- CNL <- ICL <- TGL
rather than putting everything into a single file, the platform-specific
bits are split into cnl/icl/tgl.c files instead. Makes the division clear
and code easier to maintain.
Layout of the patchset:
First are two changes combined together address the sound-clipping
problem, present when only one stream is running - specifically one
CAPTURE stream.
Follow up is naming-scheme adjustment for some of the existing functions
what improves code incohesiveness. As existing IPC/IRQ code operates
solely on cAVS 1.5 architecture, it needs no abstraction. The situation
changes when newer platforms come into the picture. Thus the next two
patches abstract the existing IPC/IRQ handlers so that majority of the
common code can be re-used.
The ICCMAX change stands out a bit - the AudioDSP firmware loading
procedure differs on ICL-based platforms (and onwards) and having a
separate commit makes the situation clear to the developers who are
going to support the solution from LTS perspective. For that reason
I decided not to merge it into the commit introducing the icl.c file.
This patch corrects a common misspelling of "request" as "reguest" found
in error log across multiple files within sound/soc/codecs.

This is a relatively quiet release, there's a lot of driver specific

one big core change was Mormioto-san's work to support more N:M

- Enhanced support for N:M CPU:CODEC mappings in the core and in
audio-graph-card2.
- Support for falling back to older SOF IPC versions where firmware for
new versions is not available.
- Support for notification of control changes generated by SOF firmware
with IPC4.
- Device tree support for describing parts of the card which can be
active over suspend (for very low power playback or wake word use
cases).
- ACPI parsing support for the ES83xx driver, reducing the number of
quirks neede for x86 systems.
- Support for more AMD and Intel systems, NXP i.MX8m MICFIL, Qualcomm
SM8250, SM8550, SM8650 and X1E80100.
- Removal of Freescale MPC8610 support, the SoC is no longer supported

The rt5645 codec driver uses DMI quirks to configure the DMIC data-pins,
which means that it knows which DMIC interface is used on a specific
device.
ATM we duplicate this DMI matching inside the UCM profiles to select
the right DMIC interface. Add a rt5645_components() helper which the
machine-driver can use to set the components string of the card so
that UCM can get the info from the components string.
This way we only need to add new DMI quirks in one place.

The value returned by an i2c driver's remove function is mostly ignored.
(Only an error message is printed if the value is non-zero that the
error is ignored.)
So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.

There is a logic error when removing rt5645 device as the function
rt5645_i2c_remove() first cancel the &rt5645->jack_detect_work and
delete the &rt5645->btn_check_timer latter. However, since the timer
handler rt5645_btn_check_callback() will re-queue the jack_detect_work,
this cleanup order is buggy.
That is, once the del_timer_sync in rt5645_i2c_remove is concurrently
run with the rt5645_btn_check_callback, the canceled jack_detect_work
will be rescheduled again, leading to possible use-after-free.
This patch fix the issue by placing the del_timer_sync function before
the cancel_delayed_work_sync.

One of the fixes reverted as part of the UMN fallout was actually fine,
however rather than undoing the revert the process that handled all this
stuff resulted in a patch which attempted to add extra error checks
instead. Unfortunately this new change wasn't really based on a good
understanding of the subsystem APIs and bypassed the usual patch flow
without ensuring it was reviewed by people with subsystem knowledge and
was merged as a fix rather than during the merge window.
The effect of the new fix is to upgrade what were previously warnings on
static data in the code to hard errors on that data. If this actually
happens then it would break existing systems, if it doesn't happen then
the change has no effect so this was not a safe change to apply as a fix
to the release candidates. Since the new code has not been tested and
doesn't in practice improve error handling revert it instead, and also
drop the original revert since the original fix was fine. This takes
the driver back to what it was in -rc1.

The Asus T100HA and T101HA 2-in-1s use a rt5645 family codec and always
report that a headset (rather then headphones) are plugged in even when
regular headphones are plugged in.
And when a headset is used, then the headset-microphone does not work.
According to RealTek the ALC3270 variant used in these devices does not
support headsets only headphones.
Since the ALC3270 is a budget version of the regular ALC5645 codec,
I assume that it is using a package with less pins and the headset-mic
pin is simply not connected.
Detect if the codec is an ALC3270 based on the ACPI HID and if it is
an ALC3270 then always report SND_JACK_MICROPHONE as false, so that
userspace will not try to use the not-connected headset-mic.

The Asus T101HA uses the default jack-detect mode 3, but instead of
using an analog microphone it is using a DMIC on dmic-data-pin 1,
like the Asus T100HA. Note unlike the T100HA its jack-detect is not
inverted.
Add a DMI quirk with the correct settings for this model.

The Medion E1239T uses the default jack-detect mode 3, but instead of
using an analog microphone it is using a DMIC on dmic-data-pin 1,
like other models following Intel's Brasswell's reference design.
This commit adds a DMI quirk pointing to the intel_braswell_platform_data
for this model.
