Subject: [media] drivers/media/dvb/dvb-usb/usb-urb.c: adjust array index
Author:  Julia Lawall <[email protected]>
Date:    Thu Jul 28 09:46:02 2011 -0300

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

A simplified version of the semantic patch that fixes this problem is as

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

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