2016-10-21[media] v4l2-core: 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>
2016-03-03[media] V4L: fix a confusing function nameGuennadi Liakhovetski
is_state_active_or_queued() actually returns true if the buffer's state is neither active nore queued. Rename it for clarity.

2014-09-21[media] videobuf: Allow reqbufs(0) to free current buffersHans de Goede
All the infrastructure for this is already there, and despite our desires for the old videobuf code to go away, it is currently still in use in 18 drivers. Allowing reqbufs(0) makes these drivers behave consistent with modern drivers, making live easier for userspace, see e.g. : https://bugzilla.gnome.org/show_bug.cgi?id=735660 Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Marek Szyprowski <m.szyprowski@samsung.com> Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
