From 41e191e85a122ad822deb7525a015410012e6c70 Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Wed, 30 Jan 2008 13:31:24 +0100 Subject: x86: replace outb_p() with udelay(2) in drivers/input/mouse/pc110pad.c replace outb_p() with udelay(2). This is a real ISA device so it likely needs this particular delay.
