There is nothing to discuss.
Dan is correct.

We have:
struct au1100fb_device {
         struct fb_info info;
...

so:

struct fb_info *info = &fbdev->info;
gets translated by the compiler to a trivial pointer math:
info = <value of fbdev> + 0     # 0 is there offset of "info" in the struct.

No crash or anything can or will happen here.

Markus, maybe you missed the "&" in front of "&fbdev->info" ?
