The patch titled
tridentfb: coding style improvement
has been removed from the -mm tree. Its filename was
tridentfb-coding-style-improvement.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: tridentfb: coding style improvement
From: Krzysztof Helt <krzysztof.h1@xxxxx>
This patch contains coding style improvements to the tridentfb driver (white
spaces, indentations, long lines).
It also moves fb_ops structure after fb api functions are defined.
