From 52e7c922f37907ab3cf3445b916fbbc53cbd6c75 Mon Sep 17 00:00:00 2001
From: Adrian Bunk <bunk@stusta.de>
Date: Mon, 12 Feb 2007 00:55:09 -0800
Subject: [PATCH] [PATCH] remove the broken FB_S3TRIO driver

The FB_S3TRIO driver:
- has been marked as BROKEN for more than two years and
- is still marked as BROKEN.

Drivers that had been marked as BROKEN for such a long time seem to be
unlikely to be revived in the forseeable future.

But if anyone wants to ever revive this driver, the code is still
present in the older kernel releases.
