The log messages for the PreSonus STUDIO 1810c about
device_setup are not applicable to the 1824c, and should
not be logged when 1824c initializes.
Refactor from if statement to switch statement as there
might be more STUDIO series devices added later.

In try_to_register_card(), the return value of usb_ifnum_to_if() is
passed directly to usb_interface_claimed() without a NULL check, which
will lead to a NULL pointer dereference when creating an invalid
USB audio device. Fix this by adding a check to ensure the interface
pointer is valid before passing it to usb_interface_claimed().

There're several different actual hardwares sold by Huawei, using the
same USB ID 12d1:3a07.
The first one we found, having a volume control named "Headset Playback
Volume", reports a min value -15360, and will mute iff setting it to
-15360. It can be simply fixed by quirk flag MIXER_PLAYBACK_MIN_MUTE,
which we have already submitted previously.[1]
The second one we found today, having a volume control named "PCM
Playback Volume", reports its min -11520 and res 256, and will mute
when less than -11008. Because of the already existing quirk flag, we
can just set its min to -11264, and the new minimum value will still
not be available to userspace, so that userspace's minimum will be the
correct -11008.

On the 1824c output channel 4 left/right is the S/PDIF output,
so this needs to be able to be set.
I'm guessing that for the 1810c since it has no output channel 4,
it does not matter what the gain value of this channel is set to.

A reasonable initial mix for the 1824c is the one that
Presonus Universal Control calls bypass.
It mutes all the physical inputs, and connects
Daw channel 1 to Line out channel 1 (left)
Daw channel 2 to Line out channel 2 (right)
Daw channel 3 to Line out channel 3 (left)
etc.
To get the most out of the 1824c a mixer application like
Universal Control is needed. One is available for linux

The previous commit 0718a78f6a ("ALSA: usb-audio: Kill timer properly at
removal") patched a UAF issue caused by the error timer.
However, because the error timer kill added in this patch occurs after the
endpoint delete, a race condition to UAF still occurs, albeit rarely.
Additionally, since kill-cleanup for urb is also missing, freed memory can
be accessed in interrupt context related to urb, which can cause UAF.
Therefore, to prevent this, error timer and urb must be killed before
freeing the heap memory.

Testing with a Presonus STUDIO 1824c together with
a Behringer ultragain digital ADAT device shows that
using all 3 altno settings works fine.
When selecting sample rate, the driver sets the interface
to the correct altno setting and the correct number of
channels is set.
Selecting the correct altno setting via Ardour, Reaper or
whatever other way to set the sample rate is more convenient
than re-loading the driver module with device_setup to
set altno.

ASoC: Updates for v6.18
A relatively quiet release for ASoC, we've had a lot of maintainance
work going on and several new drivers but really the most remarkable
thing is that we removed a driver, the WL1273 driver used in some old
Nokia systems that have had the underlying system support removed from
the kernel.
- Morimoto-san continues his work on cleanups of the core APIs and
enforcement of abstraction layers.
- Lots of cleanups and conversions of DT bindings.
- Substantial maintainance work on the Intel AVS drivers.
- Support for Qualcomm Glymur and PM4125, Realtek RT1321, Shanghai
FourSemi FS2104/5S, Texas Instruments PCM1754.
- Remove support for TI WL1273.
The sanity check previously added to uaudio_transfer_buffer_setup()
assumed the allocated buffer being linear-mapped. But the buffer
allocated via usb_alloc_coherent() isn't always so, rather to be used
with (SG-)DMA API. This leaded to a false-positive warning and the
driver failed to work.
Actually uaudio_transfer_buffer_setup() deals only with the DMA-API
addresses for MEM_XFER_BUF type, while other callers of
uaudio_iommu_map() are with pages with physical addresses for
MEM_EVENT_RING and MEM_XFER_RING types. So this patch splits the
mapping helper function to two different ones, uaudio_iommu_map() for
the DMA pages and uaudio_iommu_map_pa() for the latter, in order to
handle mapping differently for each type. Along with it, the
unnecessary address check that caused probe error is dropped, too.

Commit 05f254a636 ("ALSA: usb-audio:
Improve filtering of sample rates on Focusrite devices") changed the
check for max_rate in a way which was overly restrictive, forcing
devices to use very high samplerates if they support them, despite
support existing for lower rates as well.
This maintains the intended outcome (ensuring samplerates selected are
supported) while allowing devices with higher maximum samplerates to be
opened at all supported samplerates.
This patch was tested with a Clarett+ 8Pre USB

The smatch tool reported a potential null pointer dereference in
tascam_midi_in_urb_complete(). The 'tascam' variable, derived from
'urb->context', was checked for nullity in one place, but dereferenced
without a check in several other places.
This patch fixes the issue by adding a null check at the beginning of
the function. If 'tascam' is null, the function now safely exits.
This prevents any potential crashes from null pointer dereferences.
It also fixes a latent bug where 'usb_put_urb()' could
be called twice for the same URB on submission failure, which would
lead to a use-after-free error.
