Thomas Zimmermann 2a81dba4b5 fbdev: Fix cfb_imageblit() for arbitrary image widths ... Commit 0d03011894 ("fbdev: Improve performance of cfb_imageblit()") broke cfb_imageblit() for image widths that are not aligned to 8-bit boundaries. Fix this by handling the trailing pixels on each line separately. The performance improvements in the original commit do not regress by this change.
