5.10-stable review patch. If anyone has any objections, please let me know.

From: Florian Eckert fe@dev.tdt.de
commit e7cbce761fe3fcbcb49bcf30d4f8ca5e1a9ee2a0 upstream.
The Advantech 2-port serial card with PCI vendor=0x13fe and device=0x0018 has a 'XR17V35X' chip installed on the circuit board. Therefore, this driver can be used instead of theu outdated out-of-tree driver from the manufacturer.
