From 1df7e0e234bef878590660267e59db62a4655ba6 Mon Sep 17 00:00:00 2001 From: "Javier M. Mellid" Date: Wed, 11 Jul 2012 15:49:37 +0200 Subject: staging: sm7xxfb: minor maintenance on sm7xx_vga_setup This patch keeps code related to sm7xx_vga_setup closed. It is useful to understand/maintain the logic behind sm7xx_vga_setup with a simple look. Tested with SM712. Signed-off-by: Javier M.
