[PATCHv2 02/10] fbdev: ssd1307fb: Use vmalloc to allocate video memory.

It makes sense to use vmalloc to allocate the video buffer since it has to be page aligned memory for using it with mmap. Also deffered io seems buggy in combination with kmalloc'ed memory (crash on unloading the module). Signed-off-by: Thomas Niederprüm --- drivers/video/fbdev/ssd1307fb.
