[PATCH 0/2] fbdev: Fix image blitting for arbitrary image widths

[Thomas Zimmermann]

Recent optimization of the fbdev image-bitting helpers broke the code for
image width that do not align with multiples of 8. Both, sys and cfb, are
affected. Fix this problem by handling the trailing pixels on each line
separately.

Tested with simpledrm and the 7x14 font.
