Subject: [PATCH] [media] bt8xx: fix memory leak
Date: Fri, 16 Dec 2016 21:31:49 +0000 [thread overview]
Message-ID: <1481923909-5418-1-git-send-email-sudipm.mukherjee@gmail.com> (raw)
If dvb_attach() fails then we were just printing an error message and
exiting but the memory allocated to state was not released.
