2019-06-24media: media/pci: set device_caps in struct video_deviceHans Verkuil
Instead of filling in the struct v4l2_capability device_caps field, fill in the struct video_device device_caps field. That way the V4L2 core knows what the capabilities of the video device are. But this only really works if all drivers use this, so convert all pci drivers in this patch. Tested with cx88-blackbird and ivtv PVR-350.

2016-10-21[media] cx18: 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>

The code assumes that gcc optimizer it and not actually create any var, but convert it to immediate access at the routines. Yet, as we want to shut up gcc warnings, let's use #define, with is the standard way to store values that will use assembler's immediate access code.
