Remove double checks, convert printk to pr_warn, and move the call to
pr_warn to the first check. The simplified version of the coccinelle
semantic patch that find this issue is as follows:
// <smpl>
@@
expression E; identifier pr; expression list es;
@@
while(...){
...
- if (E) break;
+ if (E){
+ pr(es);
+ break;
+ }
...
}
- if(E) pr(es);
// </smpl>
Tested by compilation only.
