2018-08-02media: dvb: convert tuner_info frequencies to HzMauro Carvalho Chehab
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.

2016-10-21[media] tuners: don't break long linesMauro Carvalho Chehab
Due to the 80-cols restrictions, and latter due to checkpatch warnings, several strings were broken into multiple lines. This is not considered a good practice anymore, as it makes harder to grep for strings at the source code. As we're right now fixing other drivers due to KERN_CONT, we need to be able to identify what printk strings don't end with a "\n". It is a way easier to detect those if we don't break long lines. So, join those continuation lines. The patch was generated via the script below, and manually adjusted if needed. </script> use Text::Tabs; while (<>) { if ($next ne "") { $c=$_; if ($c =~ /^\s+\"(.*)/) { $c2=$1; $next =~ s/\"\n$//; $n = expand($next); $funpos = index($n, '('); $pos = index($c2, '",'); if ($funpos && $pos > 0) { $s1 = substr $c2, 0, $pos + 2; $s2 = ' ' x ($funpos + 1) . substr $c2, $pos + 2; $s2 =~ s/^\s+//; $s2 = ' ' x ($funpos + 1) . $s2 if ($s2 ne ""); print unexpand("$next$s1\n"); print unexpand("$s2\n") if ($s2 ne ""); } else { print "$next$c2\n"; } $next=""; next; } else { print $next; } $next=""; } else { if (m/\"$/) { if (!m/\\n\"$/) { $next=$_; next; } } } print $_; } </script> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

2014-07-22[media] xc4000: Fix get_frequency()Mauro Carvalho Chehab
The programmed frequency on xc4000 is not the middle frequency, but the initial frequency on the bandwidth range. However, the DVB API works with the middle frequency. This works fine on set_frontend, as the device calculates the needed offset. However, at get_frequency(), the returned value is the initial frequency. That's generally not a big problem on most drivers, however, starting with changeset 6fe1099c7aec, the frequency drift is taken into account at dib7000p driver. This broke support for PCTV 340e, with uses dib7000p demod and xc4000 tuner. Cc: stable@vger.kernel.org Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>

2012-12-27[media] tuners/xc4000: Replace memcpy with struct assignmentEzequiel Garcia
This kind of memcpy() is error-prone. Its replacement with a struct assignment is prefered because it's type-safe and much easier to read. Found by coccinelle. Hand patched and reviewed. Tested by compilation only. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ identifier struct_name; struct struct_name to; struct struct_name from; expression E; @@ -memcpy(&(to), &(from), E); +to = from; // </smpl> Signed-off-by: Peter Senna Tschudin <peter.senna@gmail.com> Signed-off-by: Ezequiel Garcia <elezegarcia@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
