From 33236415ece63d5689411f3ddb676eeb93af2698 Mon Sep 17 00:00:00 2001 From: Fabian Frederick Date: Thu, 9 Apr 2015 22:58:04 +0200 Subject: [PATCH] scripts/coccinelle/misc/bugon.cocci: update bug_on conversion warning if()/BUG conversion to BUG_ON must be avoided when there's side effect in condition. The reason being BUG_ON won't execute the condition when CONFIG_BUG is not defined. Inspired-by: J.
