Use the standard print API with dev_*() instead of the old house-baked
one. It gives better information and allows dynamically control of
debug prints.
Some debug prints are cleaned up with a macro, too.

The assignment of mpu->rmidi was moved to an earlier place, so that

The code is obtaining a GPIO reset using the reset GPIO
name "reset-gpios", but the gpiolib is already adding the
suffix "-gpios" to anything passed to this function and
will be looking for "reset-gpios-gpios" which is most
certainly not what the author desired.
Fix it up.

The tas2781-i2c driver gets an IRQ from either ACPI or device tree,
then proceeds to check if the IRQ has a corresponding GPIO and in
case it does enforce the GPIO as input and set a label on it.
This is abuse of the API:
- First we cannot guarantee that the numberspaces of the GPIOs and
the IRQs are the same, i.e that an IRQ number corresponds to
a GPIO number like that.
- Second, GPIO chips and IRQ chips should be treated as orthogonal
APIs, the irqchip needs to ascertain that the backing GPIO line
is set to input etc just using the irqchip.
- Third it is using the legacy <linux/gpio.h> API which should not
be used in new code yet this was added just a year ago.
Delete the offending code.
If this creates problems the GPIO and irqchip maintainers can help
to fix the issues.
It *should* not create any problems, because the irq isn't
used anywhere in the driver, it's just obtained and then
left unused.

When a MIDI 1.0 protocol is specified in a GTB entry while others are
set in MIDI 2.0, it should be seen as a legacy MIDI 1.0 port. Since
recently we allow drivers to set a flag SNDRV_UMP_BLOCK_IS_MIDI1 to a
FB for that purpose. This patch tries to set that flag when the
device shows such a configuration.

It's valid to give different protocols via multiple GTBs; e.g. a MIDI
1.0 port is embedded in a MIDI 2.0 device that talks with MIDI 2.0
protocol. However, the current driver implementation assumes only a
single protocol over the whole Endpoint, and it can't handle such a
scenario.
This patch changes the driver's behavior to parse GTBs to accept
multiple protocols. Instead of switching to the last given protocol,
it adds the protocol capability bits now. Meanwhile, the default
protocol is chosen by the first given protocol in GTBs.
Practically seen, this should be a minor issue, as new devices should
specify the protocols properly via UMP Endpoint Info messages, so this
is rather just covering a corner case.

For an invalid input value that is out of the given range, currently
USB-audio driver corrects the value silently and accepts without
errors. This is no wrong behavior, per se, but the recent kselftest
rather wants to have an error in such a case, hence a different
behavior is expected now.
This patch adds a sanity check at each control put for the standard
mixer types and returns an error if an invalid value is given.
Note that this covers only the standard mixer types. The mixer quirks
that have own control callbacks would need different coverage.

The UMP v1.1 spec says in the section 6.2.1:
"If a UMP Endpoint declares MIDI 2.0 Protocol but a Function Block
represents a MIDI 1.0 connection, then may optionally be used for
messages to/from that Function Block."
It implies that the driver can (and should) keep MIDI 1.0 CVM
exceptionally for those FBs even if UMP Endpoint is running in MIDI
2.0 protocol, and the current driver lacks of it.
This patch extends the sequencer port info to indicate a MIDI 1.0
port, and tries to send/receive MIDI 1.0 CVM as is when this port is
the source or sink. The sequencer port flag is set by the driver at
parsing FBs and GTBs although application can set it to its own
user-space clients, too.

Use the late-read buffer in the CS35L56 SoundWire interface to
read OTP memory.
The OTP memory has a longer access latency than chip registers
and cannot guarantee to return the data value in the SoundWire
control response if the bus clock is >4.8 MHz. The Cirrus
SoundWire peripheral IP exposes the bridge-to-bus read buffer
and status bits. For a read from OTP the bridge status bits are
polled to wait for the OTP data to be loaded into the read buffer
and the data is then read from there.

drivers probe successfully.
Note that I'm just assuming that this is a 2.0 codec based on the fact
that this device uses the older register layout.

When the CS35L41 loads its firmware, it has a number of controls to
affect its behaviour. Currently, these controls are exposed as ALSA
Controls.
These controls were never intended to be exposed to users but the
firmware doesn't mark them hidden, so make the driver ignore them.
Any changes in the coefficients handled by these controls needs to
be matched to the individual system by SSID, which is already handled
using the tuning file, when firmware is loaded, so UCM should not be
setting these controls anyway.

In order to constify `snd_soc_component_driver` struct, duplicate
`soc_component_dev_cs43130` into a `soc_component_dev_cs43130_digital` and
`soc_component_dev_cs43130_analog`.
These 2 new structures share the same .dapm_widgets and .dapm_routes
arrays but differ for .num_dapm_widgets and .num_dapm_routes.
In the digital case, the last entries are not taken into account.
Doing so has several advantages:
- `snd_soc_component_driver` can be declared as const to move their
declarations to read-only sections.
- code in the probe is simpler. There is no need to concatenate some
arrays to handle the "analog" case
- this saves some memory because all_hp_widgets and analog_hp_routes can
be removed.

The microphone/speaker privacy shutter ALSA control handlers need to
call pm_runtime_resume, since the hardware needs to be powered up to
check the hardware state of the shutter. The IRQ handler for the
shutters also needs to notify the ALSA control to inform user-space
the shutters updated. However this leads to a mutex inversion,
between the sdw_dev_lock and the controls_rwsem.
To avoid this mutex inversion cache the kctl pointers before the IRQ
handler, which avoids the need to lookup the control and take the
controls_rwsem.
