Subject: [PATCH 4/5] drivers/bluetooth: change simple_strtol to simple_strtoul

From: Julia Lawall <[email protected]>

Since size, addr, fcs, and tmp are unsigned, it would seem better to use
simple_strtoul that simple_strtol.

A simplified version of the semantic patch that makes this change is as
follows: (http://www.emn.fr/x-info/coccinelle/)

// <smpl>
@r2@
long e;
position p;
@@

e = simple_strtol@p(...)

@@
position p != r2.p;
type T;
T e;
@@

e =
- simple_strtol@p
+ simple_strtoul
(...)
// </smpl>
