From e2e324d70defce7ffc4668085dc3c8ae580074e5 Mon Sep 17 00:00:00 2001

Subject: [PATCH 2/3] [media] r820t: remove redundant initializations in
r820t_attach()
fe->tuner_priv and fe->ops.tuner_ops are initialized twice in r820t_attach().
Remove the redundant initializations and also move fe->ops.tuner_ops
initialization outside of the mutex lock (as in the xc4000 tuner code for example).
