[PATCH] media: uvcvideo: Add quirk for Luxvisions RGB Camera (30c9:0122)
From: Kean Ren
Date: Thu Sep 03 2026 - 05:21:32 EST
The device binds cleanly but delivers no image data; USB autosuspend is
suspending the streaming endpoint. Disable autosuspend for it.
Issue found on Lenovo ThinkPad X13 (codename Zelda, Intel); confirmed
working with this quirk.
