From e09ed099d0169ac3a22b17cfeece0fa54a9e43eb Mon Sep 17 00:00:00 2001 From: Krzysztof Helt Date: Wed, 23 Jul 2008 21:30:51 -0700 Subject: [PATCH] tridentfb: convert fb_info into allocated one This patch converts fb_info structure from global variable to allocatable one. The global default_par is moved into function variable. Signed-off-by: Krzysztof Helt Cc: "Antonino A.
