From 9583c099b4a08b49e03f7b461c344b6d277fd262 Mon Sep 17 00:00:00 2001 From: Jesse Barnes Date: Wed, 10 Dec 2008 15:47:28 -0800 Subject: Revert "Merge branch 'modesetting-gem'" This reverts commit 6656db10551bbb8770dd945b6d81d5138521f208. We really just want the libdrm and ioctl bits, not all the driver stuff. --- linux-core/dvo_tfp410.c | 335 ------------------------------------------------ 1 file changed, 335 deletions(-) delete mode 100644 linux-core/dvo_tfp410.c (limited to 'linux-core/dvo_tfp410.c') diff --git a/linux-core/dvo_tfp410.c b/linux-core/dvo_tfp410.c deleted file mode 100644 index 207fda80..00000000 --- a/linux-core/dvo_tfp410.c +++ /dev/null @@ -1,335 +0,0 @@ -/* - * Copyright © 2007 Dave Mueller - * - * Permission is hereby granted, free of charge, to any person obtaining a - * copy of this software and associated documentation files (the "Software"), - * to deal in the Software without restriction, including without limitation - * the rights to use, copy, modify, merge, publish, distribute, sublicense, - * and/or sell copies of the Software, and to permit persons to whom the - * Software is furnished to do so, subject to the following conditions: - * - * The above copyright notice and this permission notice (including the next - * paragraph) shall be included in all copies or substantial portions of the - * Software. - * - * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR - * IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, - * FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
