From aaa10eb1d0034eccc096f583fe308f0921617598 Mon Sep 17 00:00:00 2001 From: Arnaud Patard Date: Wed, 25 Apr 2012 12:17:24 +0200 Subject: [PATCH] 8250_pci: fix pch uart matching The rules used to make 8250_pci "ignore" the PCH uarts are lacking pci subids entries, preventing it to match and thus is breaking serial port support for theses systems. This has been tested on a nanoETXexpress-TT, which has a specifici uart clock.
