The 'from' variable at preview_config() expects an __user * type.
However, the logic there does:
from = *(void * __user *) ((void *)cfg + attr->config_offset);
With actually means a void pointer, pointing to a void __ user
pointer. When the first pointer is de-referenced with *(foo),
the type it returns is "void *" instead of "void __user *".
Change it to:
from = *(void __user **) ((void *)cfg + attr->config_offset);
in order to obtain, when de-referenced, a void __user pointer,
as desired.
That prevent those warnings:
