Subject: [PATCH 4/4] IB: Remove redundant error check
Date: Sat, 17 May 2014 20:23:00 +0200 [thread overview]
Message-ID: <1400350980-30455-4-git-send-email-peter.senna@gmail.com> (raw)
Remove double checks, and move calls to pr_err and printk to the
first check. The simplified version of the coccinelle semantic
patch that fixes this issue is as follows:
// <smpl>
@@
expression E; identifier pr; expression list es;
@@
for(...;...;...){
...
- if (E) break;
+ if (E){
+ pr(es);
+ break;
+ }
...
}
- if(E) pr(es);
// </smpl>
Tested by compilation only.
