From 7e910357f620bbebe5c5cb038b70d408e624522f Mon Sep 17 00:00:00 2001 From: Peter Senna Tschudin Date: Mon, 19 May 2014 12:26:52 +0200 Subject: atm: idt77252: Remove redundant error check 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: // @@ expression E; identifier pr; expression list es; @@ while(...){ ... - if (E) break; + if (E){ + pr(es); + break; + } ... } - if(E) pr(es); // Tested by compilation only.
