** Description changed: [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. https://lore.kernel.org/lkml/[email protected]/T/#u + v2 https://patchwork.kernel.org/project/linux-input/patch/[email protected]/ [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.
