From 29874f44fbcbc24b231b42c9956f8f9de9407231 Mon Sep 17 00:00:00 2001 From: Shaohua Li Date: Wed, 18 Nov 2009 15:15:02 +0800 Subject: drm/i915: fix gpio register detection logic for BIOS without VBT if no VBT is present, crt_ddc_bus will be left at 0, and cause us to use that for the GPIO register offset. That's never a valid register offset, so let the "undefined" value be 0 instead of -1.
