Mauro Carvalho Chehab f1b1eabff0 media: dvb: represent min/max/step/tolerance freqs in Hz
Right now, satellite frontend drivers specify frequencies in kHz,
while terrestrial/cable ones specify in Hz. That's confusing
for developers.

However, the main problem is that universal frontends capable
of handling both satellite and non-satelite delivery systems
are appearing. We end by needing to hack the drivers in
order to support such hybrid frontends.

So, convert everything to specify frontend frequencies in Hz.

Mauro Carvalho Chehab a3f90c75b8 media: dvb: convert tuner_info frequencies to Hz
Right now, satellite tuner drivers specify frequencies in kHz,
while terrestrial/cable ones specify in Hz. That's confusing
for developers.

However, the main problem is that universal tuners capable
of handling both satellite and non-satelite delivery systems
are appearing. We end by needing to hack the drivers in
order to support such hybrid tuners.

So, convert everything to specify tuner frequencies in Hz.

Plese notice that a similar patch is also needed for frontends.

Mauro Carvalho Chehab 4521af7811 media: ix2505v: get rid of /** comments
As warned:

  drivers/media/dvb-frontends/ix2505v.c:24: warning: cannot understand function prototype: 'int ix2505v_debug; '

  drivers/media/dvb-frontends/ix2505v.c:128: warning: No description found for parameter 'fe'

None of the comments there are kernel-doc. So, remove them with:

	perl -pi -e 's,\/\*\*,/*,g' drivers/media/dvb-frontends/ix2505v.c

Sakari Ailus bcb63314e2 [media] media: Drop FSF's postal address from the source code files
Drop the FSF's postal address from the source code files that typically
contain mostly the license text. Of the 628 removed instances, 578 are
outdated.

The patch has been created with the following command without manual edits:

git grep -l "675 Mass Ave\|59 Temple Place\|51 Franklin St" -- \
	drivers/media/ include/media|while read i; do i=$i perl -e '
open(F,"< $ENV{i}");
$a=join("", <F>);
$a =~ s/[ \t]*\*\n.*You should.*\n.*along with.*\n.*(\n.*USA.*$)?\n//m
	&& $a =~ s/(^.*)Or, (point your browser to) /$1To obtain the license, $2\n$1/m;
close(F);
open(F, "> $ENV{i}");
print F $a;
close(F);'; done

Mauro Carvalho Chehab f2709c206d Revert "[media] dvb_frontend: merge duplicate dvb_tuner_ops.release implementations"
While this patch sounded a good idea, unfortunately, it causes
bad dependencies, as drivers that would otherwise work without
the DVB core will now break:

ERROR: "dvb_tuner_simple_release" [drivers/media/tuners/tea5767.ko] undefined!
ERROR: "dvb_tuner_simple_release" [drivers/media/tuners/tea5761.ko] undefined!

ERROR: "dvb_tuner_simple_release" [drivers/media/tuners/fc0011.ko] undefined!

So, we have to revert it.

Note: as the argument for the release ops changed from "int"
to "void", we needed to change it at the revert patch, to
avoid compilation issues like:
	drivers/media/tuners/tea5767.c:437:23: error: initialization from incompatible pointer type [-Werror=incompatible-pointer-types]
	  .release           = tea5767_release,
	                       ^~~~~~~~~~~~~~~

This reverts commit 22a613e898.

Max Kellermann 22a613e898 [media] dvb_frontend: merge duplicate dvb_tuner_ops.release implementations
Most release callback functions are identical: free the "tuner_priv"
and clear it.  Let's eliminate some bloat by providing this simple
implementation in the dvb_frontend library.

Julia Lawall 14c4bf3c6f [media] dvb-frontends: constify dvb_tuner_ops structures
These structures are only used to copy into other structures, so declare
them as const.
