Mauro Carvalho Chehab 751dc8c7fa [media] dib0090: Fix a warning at dib0090_set_EFUSE
The check if the values for c, h and n are within the range is
always true, as, if one of this values is out of range, the
previous "if" clauses will default to a value within the
range.

That fixes the following warning:

	drivers/media/dvb-frontends/dib0090.c: In function 'dib0090_set_EFUSE':
	drivers/media/dvb-frontends/dib0090.c:1545:5: warning: comparison is always true due to limited range of data type [-Wtype-limits]

and makes the code easier to read.

Mauro Carvalho Chehab 746f7ae0e9 [media] dib8000: Fix sub-channel range
isdbt_sb_subchannel is unsigned with 8 bits. So, it will
never be -1. Instead, any value bigger than 13 is invalid.

As is, the current code generates the following warnings:

drivers/media/dvb-frontends/dib8000.c: In function 'dib8000_set_isdbt_common_channel':
drivers/media/dvb-frontends/dib8000.c:2358:3: warning: comparison is always true due to limited range of data type [-Wtype-limits]
drivers/media/dvb-frontends/dib8000.c: In function 'dib8000_tune':
drivers/media/dvb-frontends/dib8000.c:3107:8: warning: comparison is always false due to limited range of data type [-Wtype-limits]
drivers/media/dvb-frontends/dib8000.c:3153:9: warning: comparison is always false due to limited range of data type [-Wtype-limits]
drivers/media/dvb-frontends/dib8000.c:3160:5: warning: comparison is always false

It should also be noticed that ARIB STD-B31, item
"3.15.6.8 Number of segments" at TMCC table defines the
value 15 for unused segment, and 14 as reserved.

So, better to change the check to consider any value
bigger than 13 to mean that sub-channels should be
disabled, fixing the warning and doing the right thing
even if an invalid value is filled by userspace.

Mauro Carvalho Chehab c82056d0b4 [media] dib8000: store dtv_property_cache in a temp var
dtv_property_cache is used on several places on very long lines.

On all places it is used, a long list of struct reference is done.

Instead of doing it, at the routines where it is used more than once,
replace it by one temporary var. That may help the compiler to
use a better code. It also makes easier to review the code, as the
lines becomes closer to 80 columns, making them a way clearer
to read.

No functional changes.

Mauro Carvalho Chehab 0562aef296 [media] mb86a20s: better name temp vars at mb86a20s_layer_bitrate()
Using 'i' for the guard interval temporary var is a bad idea, as
'i' is generally used by "anonymous" indexes.
Let's rename modulation, fec and guard interval temp vars with
a meaningful name, as that makes easier to understand the code
and avoids cut-and-paste types of error.

Mauro Carvalho Chehab 48a8a03b58 [media] cx88: kernel bz#9476: Fix tone setting for Nova-S+ model 92001
Hauppauge Nova-S-Plus DVB-S model 92001 does not lock on horizontal
polarisation. According with the info provided at the BZ, model
92002 does.

The difference is that, on model 92001, the tone select is done via
isl6421, while, on other devices, this is done via cx24123 code.
This patch adds a way to override the demod's set_tone at isl6421
driver. In order to avoid regressions, the override is enabled
only for cx88 Nova S plus model 92001. For all other models and
devices, the set_tone is provided by the demod driver.

Patch originally proposed at bz@9476[1] by Michel Meyers and
John Donoghue but applying the original patch would break support
for all other devices based on isl6421.
