drivers/atm/firestream.c: Fix unsigned return type
The function has an unsigned return type, but returns a negative constant
to indicate an error condition. The result of calling the function is
always stored in a variable of type (signed) int, and thus unsigned can be
dropped from the return type.
A sematic match that finds this problem is as follows:
(http://coccinelle.lip6.fr/)
// <smpl>
@exists@
identifier f;
constant C;
@@
unsigned f(...)
{ <+...
* return -C;
...+> }
// </smpl>
