[PATCH] serial: 8250_pci: skip WCH PCI serial devices
From: Jiawei liu
Date: Tue Apr 28 2026 - 04:32:27 EST
WCH PCI serial devices implement vendor-specific extensions
beyond the standard 16C550 UART. These are not supported by
the generic 8250 PCI driver, and binding them may lead to
incorrect or suboptimal operation.
Skip these devices during probe to avoid misbinding.
