From 8d5f7b4353dae4c7ee342c61303372fd996ca161 Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Sat, 11 Jun 2005 09:45:30 +1000 Subject: [PATCH] radeonfb: don't blow up VGA console on load The current radeonfb memset's the framebuffer to 0 when loaded. This removes occasional artifacts but has the nasty side effect that if you load radeonfb without framebuffer console, you destroy the VGA text buffer, font, etc... radeon must not touch the framebuffer content when it doesn't "own" it.
