[ Upstream commit 1a8953f4f7746c6a515989774fe03047c522c613 ]
MARTLINKTECHNOLOGY is a microphone device, when the HID interface in an audio device is requested to get specific report id, the following error may occur.

Ignore HID interface. The device is working properly.

**YES**
This commit should be backported to stable kernel trees. Here's my extensive analysis:
1. **The commit fixes a real user-visible bug**: The device causes repeated USB interface timeout errors (`usb_set_interface failed (-110)`) that spam the kernel log and potentially interfere with device operation. The error log shows five consecutive timeout failures over 25 seconds, which would significantly impact user experience.
2. **The fix is minimal and contained**: The code changes are extremely simple - just adding two lines to define the vendor/device ID in `hid-ids.h` and one line to add it to the `hid_ignore_list[]` array in `hid-quirks.c`. This is the standard pattern for HID quirks.
3. **Similar commits were backported**: This is very similar to "Similar Commit #1" (Logitech GROUP) which also dealt with HID interfaces on audio devices causing problems. That commit added `HID_QUIRK_NOGET` and was backported. The pattern is identical - an audio device with a problematic HID interface that needs to be handled via quirks.
4. **No risk of regression**: The change only affects devices with vendor ID 0x4c4a and product ID 0x4155. When a device matches this ID, the HID subsystem will simply skip it via the `hid_ignore()` function check in `hid_add_device()`. This cannot affect any other devices.
5. **The device functions properly with the fix**: The commit message explicitly states "The device is working properly" - meaning the audio functionality works fine once the HID interface is ignored. This is not breaking functionality but rather preventing the HID subsystem from interfering with a working audio device.
6. **The error pattern indicates a hardware quirk**: The continuous timeout errors (-110) when trying to set the USB interface suggests the device's HID implementation doesn't properly respond to standard HID commands. This is exactly the type of hardware-specific issue that the HID quirks system was designed to handle.
This meets all the criteria for stable backporting: it fixes a bug affecting users, is small and self-contained, has minimal risk, and follows established patterns for similar fixes that were previously backported.
