[PATCH 2/2] pseries: remove dead eeh video code
From: Linas Vepstas <hidden>
Date: 2007-08-09 23:28:14
Remove dead code, and a misleading comment about EEH checking for video devices. The removed code is a left-over from the olden days where there was concern over how video devices worked in Linux. We are never going to go that way again, so kill this.
