From 50d16ca29bd2ccbca08e4f74fe1d9618c735c22f Mon Sep 17 00:00:00 2001 From: Alexander Stein Date: Tue, 25 Mar 2014 14:05:08 +0100 Subject: [PATCH] pch_uart: Add uart device to irq name This will additionally show the specific UART device instead of the general module name. This cames in handy so check for the interupts of a specific device if there are several of them.
