[PATCH 2/3] HID: quirks: Ignore Valkyrie USB LCD devices

From: ZiAo Wang

Date: Wed Oct 28 2026 - 09:27:26 EST


Valkyrie USB LCD devices (0x345f:0x9132) expose a HID interface
for vendor-specific display control commands and a separate USB
interface for bulk framebuffer transfers.

The HID interface is not intended for input and should be managed
by the dedicated USB display driver instead of the HID subsystem.

Add the device to the HID quirk table with HID_QUIRK_IGNORE to
prevent the HID driver from binding to it.
