2016-10-21[media] zr364xx: don't break long linesMauro Carvalho Chehab1-4/+2
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>

2015-06-09[media] usb drivers: use BUG_ON() instead of if () BUGMauro Carvalho Chehab1-2/+1
Some USB drivers have a logic at the VB buffer handling like: if (in_interrupt()) BUG(); Use, instead: BUG_ON(in_interrupt()); Btw, this logic looks weird on my eyes.

2014-12-23[media] media: drivers shouldn't touch debug field in video_deviceHans Verkuil1-2/+0
The debug field in struct video_device is for internal use only and drivers should mix that with their own debug module options. It is handled by the V4L2 core and users can set it using /sys/class/video4linux/<devX>/debug. It has been deprecated for some time now, so it is time to remove it completely from the drivers.

2014-07-17[media] v4l: Support extending the v4l2_pix_format structureLaurent Pinchart1-3/+0
The v4l2_pix_format structure has no reserved field. It is embedded in the v4l2_framebuffer structure which has no reserved fields either, and in the v4l2_format structure which has reserved fields that were not previously required to be zeroed out by applications. To allow extending v4l2_pix_format, inline it in the v4l2_framebuffer structure, and use the priv field as a magic value to indicate that the application has set all v4l2_pix_format extended fields and zeroed all reserved fields following the v4l2_pix_format field in the v4l2_format structure. The availability of this API extension is reported to userspace through the new V4L2_CAP_EXT_PIX_FORMAT capability flag. Just checking that the priv field is still set to the magic value at [GS]_FMT return wouldn't be enough, as older kernels don't zero the priv field on return. To simplify the internal API towards drivers zero the extended fields and set the priv field to the magic value for applications not aware of the extensions.
