[media] af9013: change & to &&
This is just a cleanup, it doesn't change how the code works. These
are compound conditions and not bitwise operations so it should be &&
and not &.

[media] dvb: Remove ops->info.type from frontends

[media] dvb: don't require a parameter for get_frontend
Just like set_frontend, use the dvb cache properties for get_frontend.
This is more consistent, as both functions are now symetric. Also,
at the places get_frontend is called, it makes sense to update the
cache.
Most of this patch were generated by this small perl script:
while (<>) { $file .= $_; }
if ($file =~ m/\.get_frontend\s*=\s*([\d\w_]+)/) {
my $get = $1;
$file =~ s/($get)(\s*\([^\,\)]+)\,\s*struct\s+dtv_frontend_properties\s*\*\s*([_\d\w]+)\)\s*\{/\1\2)\n{\n\tstruct dtv_frontend_properties *\3 = &fe->dtv_property_cache;/g;
}
print $file;
Of course, the changes at dvb_frontend.[ch] were made by hand,
as well as the changes on a few other places, where get_frontend()
is called internally inside the driver.
On some places, get_frontend() were just a void function. Those
occurrences were removed, as the DVB core handles such cases.

[media] dvb-core: add support for a DVBv5 get_frontend() callback

After the conversion for all drivers, get_frontend_legacy()

[media] Rename set_frontend fops to set_frontend_legacy
Passing DVBv3 parameters to set_frontend is not fun, as the
core doesn't have any way to know if the driver is using the
v3 or v5 parameters. So, rename the callback and add a new
one to allow distinguish between a mixed v3/v5 paramenter call
from a pure v5 call.
After having all frontends to use the new way, the legacy
call can be removed.

[media] tuners: remove dvb_frontend_parameters from set_params()
This is a big patch, yet trivial: now that all tuners use the DVBv5
way to pass parameters (e. g. via fe->dtv_property_cache), the
extra parameter can be removed from set_params() call.
After this change, very few DVBv3 specific stuff are left at the
tuners.

IF freq for DVB-T 7 MHz and 8 MHz was set slightly wrong. Due to that it

was dropped for 8 MHz channels.
That bug was pointed by few people during last two months. Thank you.
Trivial fix. Compile tested only due to lack of proper HW and signal.
