[PATCH] non-linear frame buffer read/write access

While the code in fbmem.c allows for hooking read/write access to
non-linear frame buffers by means of fb_read and fb_write in struct fb_ops,
I could not find a way tho access the actual frame buffer memory from
within these routines.  I therefore had to patch fbmem.c, to be able to
retrieve a pointer to struct fb_info from the 'file' argument to these
functions.

The second hunk of the patch is not strictly required, I only did that for
symmetry reasons (and the code is somewhat shorter).
