2016-10-21[media] videodev2.h Add HSV formatsRicardo Ribalda Delgado1-0/+2
These formats store the color information of the image in a geometrical representation. The colors are mapped into a cylinder, where the angle is the HUE, the height is the VALUE and the distance to the center is the SATURATION. This is a very useful format for image segmentation algorithms.

Don't complain about a failure to compute the pre_pll divisor. The function is used to determine whether a particular combination of bits per sample value and a link frequency can be used, in which case there are lots of unnecessary driver messages. During normal operation the failure generally does not happen. Use dev_dbg() instead.

2016-10-21[media] s5p-mfc: fix failure path of s5p_mfc_alloc_memdev()Marek Szyprowski1-0/+1
s5p_mfc_alloc_memdev() function lacks proper releasing of allocated device in case of reserved memory initialization failure.

2016-10-21[media] tveeprom: use dev_foo() for printk messagesMauro Carvalho Chehab1-52/+24
Instead of calling a V4L-specific macro, do the right thing and use the dev_foo() macros. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-10-21[media] tuners: don't break long linesMauro Carvalho Chehab9-65/+39
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>
