+Subject: [PATCH 1/2] GDBusWorker: continue_writing: initialize
+ flush_async_data if closing
+
+This was a regression in commit f41178c6c: flush_async_data wasn't
+necessarily NULL in the "don't flush" case.
+
+Also move initialization of these variables up so that it's
+unconditional, since that's easier to verify than checking
+that each branch gets it right.
+
