Add ioctls:
- SCARLETT2_IOCTL_SELECT_FLASH_SEGMENT
- SCARLETT2_IOCTL_ERASE_FLASH_SEGMENT

The settings or the firmware flash segment can be selected and then
erased (asynchronous operation), and the erase progress can be
monitored.

If the erase progress is not monitored, then subsequent hwdep
operations will block until the erase is complete.

Once the erase is started, ALSA controls that communicate with the
device will all return -EBUSY, and the device must be rebooted.

Increase the quirk delay from 2 seconds to 4 seconds. This reflects a
change in the Windows driver in which the delay was increased to about

Also clarify in the quirk comment that the quirk is only applied to
older devices (USB ID 07fd:0008).

3473185f31 ALSA: scarlett2: Remap Level Meter values
The values previously returned by the Level Meter control were passed
through from the interface without interpretation, but it has been
discovered that the order of the values matches the mux assignment
order (which is not presented to userspace). In addition, the values
for disabled mux outputs, and mux outputs which share a source are
invalid.

This patch adds a per-device meter_map[], and a dynamic
meter_level_map[] which is updated on routing changes. The meter level
map gets used by scarlett2_meter_ctl_get() to both present the values
in a standard order, and to fix up the invalid values by zeroing them
(for disabled outputs) and copying them (for mux outputs which share a
source).

I own an external usb Webcam, model NexiGo N930AF, which had low mic volume and
inconsistent sound quality. Video works as expected.

Based on the usb data about manufacturer, SPCA2281B3 is the most likely controller IC
Manufacturer does not provide link for datasheet nor detailed specs.
No way to confirm if the firmware supports any other way of getting the sample rate.

Testing patch provides consistent good sound recording quality and volume range.

b61a3acada ALSA: scarlett2: Add Focusrite Clarett+ 2Pre and 4Pre support
The Focusrite Clarett+ series uses the same protocol as the Scarlett
Gen 2 and Gen 3 series. This patch adds support for the Clarett+ 2Pre
and Clarett+ 4Pre similarly to the existing 8Pre support by adding
appropriate entries to the scarlett2 driver.

The Clarett 2Pre USB and 4Pre USB presumably use the same protocol as
well, so support for them can easily be added if someone can test.

6a83d6f3bb ALSA: usb-audio: Fix microphone sound on Opencomm2 Headset
When a Opencomm2 Headset is connected to a Bluetooth USB dongle,
the audio playback functions properly, but the microphone does not work.

In the dmesg logs, there are messages indicating that the init_pitch
function fails when the capture process begins.

The microphone only functions when the ep pitch control is not set.

Toggling the pitch control off bypasses the init_piatch function
and allows the microphone to work.

f5cc9cdfc9 ALSA: usx2y: Annotate struct snd_usx2y_urb_seq with __counted_by
Prepare for the coming implementation by GCC and Clang of the __counted_by
attribute. Flexible array members annotated with __counted_by can have
their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS
(for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family
functions).

As found with Coccinelle[1], add __counted_by for struct snd_usx2y_urb_seq.
Additionally, since the element count member must be set before accessing
the annotated flexible array member, move its initialization earlier.

For suppressing the warning, replace snprintf() with scnprintf().

6e743781d6 ALSA: scarlett2: Add correct product series name to messages
This driver was originally developed for the Focusrite Scarlett Gen 2
series, but now also supports the Scarlett Gen 3 series, the
Clarett 8Pre USB, and the Clarett+ 8Pre. The messages output by the
driver on initialisation and error include the identifying text
"Scarlett Gen 2/3", but this is no longer accurate, and writing
"Scarlett Gen 2/3/Clarett USB/Clarett+" would be unwieldy.

Add series_name field to the scarlett2_device_entry struct so that
concise and accurate messages can be output.

bc83058f59 ALSA: scarlett2: Default mixer driver to enabled
Early versions of this mixer driver did not work on all hardware, so
out of caution the driver was disabled by default and had to be
explicitly enabled with device_setup=1.

Since commit 764fa6e686 ("ALSA: usb-audio: scarlett2: Fix device
hang with ehci-pci") no more problems of this nature have been
reported. Therefore, enable the driver by default but provide a new
device_setup option to disable the driver in case that is needed.

- device_setup value of 0 now means "enable" rather than "disable".
- device_setup value of 1 is now ignored.
- device_setup value of 4 now means "disable".
