+Subject: [PATCH] Ignore clang warning about address of temp in
+ config.tests/bluez
+
+There is a similar error with gcc which is suppressed by using
+-fpermissive, clang however is more concerned and has specific flag for
+it, this flag is not implemented in gcc so we can not use it via general
+cmdline options to compiler, so resort to using diagnostic pragma
+
+Upstream-Status: Pending
