[PATCH 1/4] sound/isa: use unsigned for loop index

[Julia Lawall <julia@diku.dk>]

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>
