[PATCH 05/12] [media] dvb_frontend: merge duplicate dvb_tuner_ops.release implementations

From: Max Kellermann
Date: Tue Aug 09 2016 - 17:43:04 EST

Most release callback functions are identical: free the "tuner_priv"
and clear it. Let's eliminate some bloat by providing this simple
implementation in the dvb_frontend library.
