Can framer be a NULL pointer? This sort of test often covers up
bugs. So either let it dereference the NULL pointer and opps, or
return -EINVAL.

Well, in the current usage, it cannot be a NULL pointer.
I will simply remove the check (every where it is present) and
dereference the pointer instead of returning -EINVAL.
