From 6ab0f5cd364476fe5cb329fd46ee41bea6d4c69c Mon Sep 17 00:00:00 2001 From: Matthew Wilcox Date: Fri, 21 Oct 2005 22:58:51 -0400 Subject: [PARISC] Update parisc specific input code from parisc tree Update drivers to new input layer changes. Signed-off-by: Helge Deller Signed-off-by: Matthew Wilcox Reorder code in gscps2_interrupt() and only enable ports when opened. This fixes issues with hangs booting an SMP kernel on my C360. Previously serio_interrupt() could be called before the lock in struct serio was initialised.
