From 140c118a9886b0386d748e6aa7cbd8ba9f9b0ede Mon Sep 17 00:00:00 2001

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.
