parport: parport_serial: add WCH device 1c00:3450 and disable IRQ
From: Jiawei liu
Date: Tue Apr 28 2026 - 04:35:53 EST
Add PCI device ID 1c00:3450 for WCH parallel port devices.
The generic parport_serial driver requests IRQs for this
device, but the interrupt handler does not properly handle
the device-generated interrupts, which may result in
spurious or unhandled IRQs.
Disable IRQ usage for this device to ensure stable operation.
