In function sm750_hw_copyarea() of sm750_accel.c, there are some comments in ASCII graphs, describing 4 possible scenarios of overlapping areas when copying an area. However, the graphs have broken indention. The entire SiliconMotion series video controllers, including SM501, SM712 and SM750 have similar 2D engines, yet, I have not seen a single version of it with ASCII graphs properly formatted... Fix the the misleading ASCII graphs. It would eliminate the confusions and improve code readability.
