If the list does not contain the expected element, the value of
list_for_each_entry() iterator will not point to a valid structure.
To avoid type confusion in such case, the list iterator
scope will be limited to list_for_each_entry() loop.

In preparation to limiting scope of a list iterator to the list traversal
loop, use a dedicated pointer to point to the found element.
Determining if an element was found is then simply checking if
the pointer is != NULL.

The drivers/usb/ portion of this patch should be in patch 1/X, right?

Also, you will have to split these up per-subsystem so that the
different subsystem maintainers can take these in their trees.

thanks,
