Subject: [PATCH] video: bmp: Fix video_splash_align_axis()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Convert panel_picture_delta and axis_alignment from unsigned long
to long to insure to store correctly the difference between
panel_size and picture_size in case the panel_size is smaller
than picture_size.
