Mauro Carvalho Chehab 7c61d80a9b [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.

Mauro Carvalho Chehab 285d55ad5f [media] stv0367: convert set_fontend to use DVBv5 parameters
Instead of using dvb_frontend_parameters struct, that were
designed for a subset of the supported standards, use the DVBv5
cache information.

Also, fill the supported delivery systems at dvb_frontend_ops
struct.

Mauro Carvalho Chehab a689e3657d [media] dvb-core: add support for a DVBv5 get_frontend() callback
Creates a DVBv5 get_frontend call, renaming the DVBv3 one to
get_frontend_legacy(), while not all frontends are converted.

After the conversion for all drivers, get_frontend_legacy()
will be removed.

Mauro Carvalho Chehab bc9cd2736b [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.

Mauro Carvalho Chehab 14d24d148c [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.

Dan Carpenter bf512b2d9c [media] stv0367: signedness bug in stv0367_get_tuner_freq()
We use err to store negative error codes so it should be signed.  And
if we return an error from stv0367_get_tuner_freq() that needs to be
handled properly as well.  (param->frequency is a u32).
