![]() The Logitech pan/tilt reset UVC control contains two V4L2 button controls to reset pan and tilt. As the UVC control is not marked as auto-update, the button bits are set but never reset. A pan reset that follows a tilt reset would thus reset both pan and tilt. Fix this by not caching the control value of write-only controls. All standard UVC controls are either readable or auto-update, so this will not cause any regression and will not result in extra USB requests.
