From 35b09c9bf619c4fc6040c52dcea6bd5bd6af7679 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Fri, 28 Oct 2011 14:42:41 +0300 Subject: drm/i915: fix if statement (bogus semi-colon) The semi-colon is a typo here and it makes the if statement unconditional.

Might be better to completely remove the work-around from the kernel in this case?
