From dcdf2f7e7e154957f913e5468e3715e1a0401138 Mon Sep 17 00:00:00 2001 From: Anatolij Gustschin Date: Fri, 13 May 2011 11:05:08 +0200 Subject: [PATCH] video: mb862xxfb: correct fix.smem_len field initialization Initialize smem_len field to the actual frame buffer size and not to the whole video RAM size. This prevents overwriting other video memory (which could be used by other layers, cursors or accelerated drivers) by frame buffer applications relying on fix.smem_len.
