+Subject: [PATCH] staging: bcm2835-codec: NULL component handle on
+ queue_setup failure
+
+queue_setup tries creating the relevant MMAL component and configures
+the input and output ports as we're expecting to start streaming.
+If the port configuration failed then it destroyed the component,
+but failed to clear the component handle, therefore release tried
+destroying the component again.
+Adds some logging should the port config fail as well.
