[Bug 2102077] Re: Run iio_info will be stucked forever (HID-SENSOR-200011.5.auto/iio:device1)

This bug is awaiting verification that the linux/6.8.0-91.92 kernel in
-proposed solves the problem. Please test the kernel and update this bug
with the results. If the problem is solved, change the tag
'verification-needed-noble-linux' to 'verification-done-noble-linux'. If
the problem still exists, change the tag 'verification-needed-noble-
linux' to 'verification-failed-noble-linux'.


If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.


See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

Bug description:
[Impact]
The Chicony Electronics HP 5MP Camera (USB ID 04F2:B82C) reports a HID
sensor interface that is not actually implemented. Attempting to access
this non-functional sensor via iio_info causes system hangs as runtime PM
tries to wake up an unresponsive sensor.

[Fix]
Add this device to the HID ignore list since the sensor interface is
non-functional by design and should not be exposed to userspace.

v2 https://patchwork.kernel.org/project/linux-input/patch/20250506055015.774509-1-acelan.kao@canonical.com/

[Test]
1. Boot up the machine with this USB camera(04F2:B82C)
2. Run iio_info, it should return the iio information immediately

[Where problems could occur]
It's a quirk dedicated to a certain USB webcam, so it won't lead to other sesnors fail to work.
