[PATCH 5/9] staging: sm7xxfb: minor maintenance on sm7xx_vga_setup

From: Javier M. Mellid
Date: Wed Jul 11 2012 - 09:50:59 EST


From: "Javier M. Mellid" <jmunhoz@xxxxxxxxxx>

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.
