From 059802f961db9717412b6958111ca1cd1865726e Mon Sep 17 00:00:00 2001 From: Peter Senna Tschudin Date: Tue, 29 Jul 2014 18:12:20 +0200 Subject: [PATCH] cpupower: Remove redundant error check Remove double checks, and move the call to print_error to the first check. Replace break by return, and return 0 on success. The simplified version of the coccinelle semantic patch that fixes this issue is as follows: // @@ expression E; identifier pr; expression list es; @@ for(...;...;...){ ... - if (E) break; + if (E){ + pr(es); + break; + } ... } - if(E) pr(es); // Signed-off-by: Peter Senna Tschudin Signed-off-by: Thomas Renninger Signed-off-by: Rafael J.
