From 205a8eb7ce713c7f1722297dd97d19dcea6f266c Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Mon, 8 Oct 2012 16:15:26 -0600 Subject: [PATCH] dtc: fix for_each_*() to skip first object if deleted The previous definition of for_each_*() would always include the very first object within the list, irrespective of whether it was marked deleted, since the deleted flag was not checked on the first object, but only on any "next" object. Fix for_each_*() to check the deleted flag in the loop body every iteration to correct this.
