Subject: [media] coda: Propagate the correct error on 
devm_request_threaded_irq()
Author:  Fabio Estevam <[email protected]>
Date:    Wed Jun 4 15:46:24 2014 -0300

If devm_request_threaded_irq() fails, we should better propagate the real error.

Also, print out the error code in the dev_err message.
