From 8af1d50f7f679375f579782f2d5eb5e2a1508df8 Mon Sep 17 00:00:00 2001
From: Krzysztof Helt <krzysztof.h1@wp.pl>

Subject: tdfxfb: coding style improvement

This patch contains coding style improvements to the tdfxfb driver (white
spaces, indentations, long lines).

It also moves fb_ops structure to the end of file, so forward declarations of
ops functions are redundant.
