From 2fbe8c7c3ebfed2059a6597322bb0dbc4d96feb5 Mon Sep 17 00:00:00 2001 From: Matthew Garrett Date: Mon, 16 Apr 2012 16:26:03 -0400 Subject: [PATCH] vga-switcheroo: Use vga_default_device() vga-switcheroo currently changes the default VGA device by fiddling with the IORESOURCE_ROM_SHADOW flag on the device. This isn't strictly accurate, since there's no guarantee that switching also changes the ROM decoding. Switch over to using the vgaarb functions for this.
