Subject[PATCH 2/4] sound/oss: use unsigned for loop index
From: Julia Lawall <julia@diku.dk>

A few more cases in the spirit of the patch "Trivial: Replacement of always
>0 ints with unsigned ints" submitted by Ricardo Martins <ricardo@scarybox.net>

The transformation was made using the following semantic patch
(http://www.emn.fr/x-info/coccinelle/)

// <smpl>
@r exists@ // find anything that might decrement the variable
identifier i;
expression E;
position p;
@@

int i@p;
...
(
&i
|
i--
|
--i
|
i-=E
|
i+=E
)

@x disable decl_init@
identifier r.i;
expression E;
position p1 != r.p;
@@

(
volatile int i = 0;
|
volatile int i;
|
+ unsigned
int i@p1 = 0;
|
+ unsigned
int i@p1;
)
<... when != i = E
(
i = 0
|
i = 1
)
...>
// </smpl>

Signed-off-by: Julia Lawall <julia@diku.dk>
