ALSA: sound/core/pcm_compat.c: adjust array index
commit ca9380fd68514c7bc952282c1b4fc70607e9fe43 upstream.
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>
