The patch titled
fbdev: Fix logo rotation if width != height
has been removed from the -mm tree. Its filename is
fbdev-fix-logo-rotation-if-width-=-height.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: fbdev: Fix logo rotation if width != height
From: "Antonino A. Daplas" <adaplas@xxxxxxxxx>
Logo drawing crashes or produces a corrupt display if the logo width and
height are not equal. The dimensions are transposed prior to the actual
rotation and the width is used instead of the height in the actual rotation
code. These produce a corrupt image.
