[PATCH 5/6] sound/core/pcm_compat.c: adjust array index

[Julia Lawall]

From: Julia Lawall <julia@xxxxxxx>

Convert array index from the loop bound to the loop index.

A simplified version of the semantic patch that fixes this problem is as
follows: (http://coccinelle.lip6.fr/)

// <smpl>
@@
expression e1,e2,ar;
@@

for(e1 = 0; e1 < e2; e1++) { <...
  ar[
- e2
+ e1
  ]
  ...> }
// </smpl>
