A malformed USB device can provide a vendor-specific interface without
any endpoint descriptors. fcp_find_fc_interface() currently selects the
first vendor-specific interface and reads endpoint 0 from it, without
checking whether the interface actually has any endpoints.

When bNumEndpoints is zero, no endpoint array is allocated for the parsed
alternate setting, so get_endpoint(..., 0) yields an invalid endpoint
descriptor pointer. Dereferencing it through usb_endpoint_num() then
triggers a NULL pointer dereference.

Skip vendor-specific interfaces that do not have any endpoints.

The laptop has a microphone mute LED on the F4 key, but it was not
taken in mind when the previous quirk was added
in commit 00e44a68efef50f65b12854b41f098b4d50f10be ("ALSA:
hda/realtek: Add quirk for Acer Nitro ANV15-41").
Replace ALC2XX_FIXUP_HEADSET_MIC with ALC245_FIXUP_ACER_MICMUTE_LED,
which enables the LED and chains the previous quirk for the headset
microphone.

ASoC: Fixes for v7.2

We've got a good collection of device specific fix here, plus a couple
of stand out things:

 - Richard fixed some special cases with the new device_link creation
   by more gracefully handling any errors during creation.
 - Charles did some light refactoring of the SoundWire interfaces to
   fix some persistent randconfig issues that people kept running into.

The back-end consumes data in units of the number of channels. When the
maxburst value is not evenly divisible by the channel count, the DMA
transfer length does not align with the FIFO frame boundary, causing
wrong data to be copied and audible noise at the end of the stream.

This is specific to eDMA: eDMA only responds to DMA requests from the
back-end, whereas SDMA handles requests from both the front-end and the
back-end and is not affected.

For eDMA, when the back-end maxburst is not evenly divisible by the
channel count, align it to the nearest valid boundary:
- If maxburst >= channel count, override to the channel count so each
  transfer corresponds to exactly one audio frame.
- If maxburst < channel count, override to 1 to avoid partial-frame
  transfers.

Retain the original maxburst for SDMA or when it already aligns with
the channel count.

If sclk is not provided the driver falls back to using bclk and prints
an info message in the system log. Under normal operations the message
is repeated many times:

[   17.929576] pcm512x 0-004c: No SCLK, using BCLK: -2
[   17.949172] pcm512x 0-004c: No SCLK, using BCLK: -2
[   17.953029] pcm512x 0-004c: No SCLK, using BCLK: -2
[   17.965059] pcm512x 0-004c: No SCLK, using BCLK: -2
[   82.592980] pcm512x 0-004c: No SCLK, using BCLK: -2
[   82.866293] pcm512x 0-004c: No SCLK, using BCLK: -2

Switch from dev_info to dev_info_once to reduce log noise.

isight_packet() takes the frame count from the device iso packet and
checks it only against the device claimed iso length.

	count = be32_to_cpu(payload->sample_count);
	if (likely(count <= (length - 16) / 4))
		isight_samples(isight, payload->samples, count);

length is the iso header data_length. It can be up to 0xffff. So the
gate allows a count up to about 16379. isight_samples() then copies
count frames out of payload->samples into the PCM DMA buffer.

payload->samples holds only 2 * MAX_FRAMES_PER_PACKET values. The
device multiplexes two samples per frame. A count past
MAX_FRAMES_PER_PACKET reads past the payload. A count past the buffer
size writes past runtime->dma_area. The smallest PCM buffer is larger
than MAX_FRAMES_PER_PACKET. Bounding the count to MAX_FRAMES_PER_PACKET
keeps both the read and the write in range.

A malicious or faulty Apple iSight on the FireWire bus reaches this
during a normal capture.

Add the MAX_FRAMES_PER_PACKET bound to the gate.

qc_usb_audio_probe() allocates svc->uaudio_svc_hdl separately from the
uaudio_qmi_svc object.

qmi_handle_release() releases the resources owned by an initialized QMI
handle, but does not free the memory containing the struct qmi_handle
itself. The probe error path and the remove path currently release the
handle and then free svc, losing the last pointer to the separately
allocated handle.

This leaks one struct qmi_handle on each affected probe unwind and on
each successful probe/remove cycle.

Free the handle after qmi_handle_release() in both paths.

Lenovo Legion 7i 16IAX7 systems with Realtek ALC287 codec SSID
17aa:3874 and CSC3551/CS35L41 speaker amps do not provide the
required CS35L41 _DSD properties in ACPI.

Without a quirk, cs35l41-hda fails probing the amps with missing
cirrus,dev-index / Platform not supported errors, leaving the built-in
speakers silent.

This model is similar to the already-supported 17AA386F Legion 7i
16IAX7 variant. Add the Realtek ALC287 quirk to select
ALC287_FIXUP_CS35L41_I2C_2 and add 17AA3874 to the CS35L41 property
table using the same two-amp external-boost configuration.

Tested on a Lenovo Legion 7 16IAX7 with Ubuntu 7.0.0-22-generic. Both
CSC3551 CS35L41 amps probe and bind, firmware loads, calibration
applies, built-in speaker playback works, and the cirrus,dev-index
failure is gone.

The DualSense jack-detection input handler verifies that a matching input
device belongs to the same physical controller by building kobject path
strings for both the input device and the USB audio device, then comparing
the path prefix.

This was observed when a weak physical connection caused the controller
to rapidly disconnect and reconnect. During that repeated hotplug,
snd_dualsense_ih_match() can run while the controller's USB device is
being disconnected. kobject_get_path() walks ancestor kobjects and
dereferences their names; if the USB device kobject name is no longer
valid, this can fault in strlen():

  RIP: 0010:strlen+0x10/0x30
  Call Trace:
   kobject_get_path+0x34/0x150
   snd_dualsense_ih_match+0x49/0xd0 [snd_usb_audio]
   input_register_device+0x566/0x6a0
   ps_probe+0xb89/0x1590 [hid_playstation]

The same ownership check can be done without building kobject path
strings. The input device is parented below the HID device, USB interface
and USB device, so walking the input device parent chain and comparing
against the mixer USB device preserves the check without dereferencing
kobject names during disconnect.
