r820t: comment out two ancillary tables

2016-06-24T15:00:02+00:00

As Gcc6.1 warned, those tables are currently unused:
	drivers/media/tuners/r820t.c:349:18: warning: 'r820t_mixer_gain_steps' defined but not used [-Wunused-const-variable=]
	 static const int r820t_mixer_gain_steps[]  = {
	                  ^~~~~~~~~~~~~~~~~~~~~~
	drivers/media/tuners/r820t.c:345:18: warning: 'r820t_lna_gain_steps' defined but not used [-Wunused-const-variable=]
	 static const int r820t_lna_gain_steps[]  = {
	                  ^~~~~~~~~~~~~~~~~~~~

They're actually used only by a routine that it is currently
commented out. So, move those tables to be together with such
code and comment them out.

[media] si2157: register as a tuner entity

2016-02-16T10:50:36+00:00

As this tuner doesn't use the usual subdev interface, we need
to register it manually.

[media] si2157: cancel_delayed_work_sync before device removal / kfree

2016-02-01T11:41:38+00:00

si2157_remove  was  calling  kfree(dev)  with  possibly  still  active
schedule_delayed_work(dev->stat_work).  This  caused kernel  panics in
call_timer_fn e.g. after rmmod cx23885.
