Pull fbdev fixes from Helge Deller:
 "Four small patches for fbdev, of which two are important: One fixes
  the bitmap font generation and the other prevents a possible
  use-after-free in udlfb:

   - Fix rotating fonts by 180 degrees (Thomas Zimmermann)

   - Drop duplicate include of linux/module.h in fb_defio (Chen Ni)

   - Add vm_ops in udlfb to prevent use-after-free (Rajat Gupta)

   - ipu-v3: clean up kernel-doc warnings (Randy Dunlap)"
