It looks at least odd to apply spin_unlock to a mutex. 

The semantic patch that makes this change is as follows:
(http://www.emn.fr/x-info/coccinelle/)

// <smpl>
@def@
declarer DEFINE_MUTEX;
identifier m;
@@

DEFINE_MUTEX(m);

@@
identifier def.m;
@@

(
- spin_lock(&m)
+ mutex_lock(&m)
|
- spin_unlock(&m)
+ mutex_unlock(&m)
)
// </smpl>
