From c28c3583679c181a03910b6356228e99fcc27167 Mon Sep 17 00:00:00 2001 From: Miloslav Trmac Date: Tue, 10 Jan 2006 01:59:07 -0500 Subject: [PATCH] Input: wistron - do not crash if BIOS does not support interface offset can never be < 0 because it has type size_t. The driver currently oopses on insmod if BIOS does not support the interface, instead of refusing to load.
