From ef1e1e0782e99c9dcf2b35e5310cdd8ca9211374 Mon Sep 17 00:00:00 2001 From: "Daniel P. Berrange" Date: Wed, 26 Aug 2015 12:17:18 +0100 Subject: maint: avoid useless "if (foo) free(foo)" pattern The free() and g_free() functions both happily accept NULL on any platform QEMU builds on. As such putting a conditional 'if (foo)' check before calls to 'free(foo)' merely serves to bloat the lines of code. Signed-off-by: Daniel P.
