From 5fba610ec94a1290fc299ea051e47d55da9059ba Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Tue, 3 Aug 2010 11:33:43 +0000 Subject: [PATCH] powerpc/powermac: Drop unnecessary null test for_each_node_by_name binds its first argument to a non-null value, and thus any null test on the value of that argument is superfluous. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // @@ iterator I; expression x,E; @@ I(x,...) { <...
