From 9bfbd739176ebc41e4ec93dcd21264b87640aa5b Mon Sep 17 00:00:00 2001 From: Nagy Gabor Date: Fri, 25 Jan 2008 21:52:35 +0100 Subject: [PATCH] Fix PM_ERR_CONFLICTING_DEPS handling in sync.c * eliminate asymmetry (innerconflict vs. outerconflict) * fix a memleak (in case of PM_ERR_MEMORY deps wasn't freed) * fix wrong pmconflict_t duplication (*retconflict = *conflict) Note: the new code introduces some code duplication which shall disappear by fixing FS#7524.
