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 $_;
}

When writing the change in commit dcc7fdbec5 ("[media] gspca:
ov534/topro: prevent a division by 0") I used magic numbers for the
default framerate to minimize the code footprint to make it easier to
backport the patch to the stable trees.
However it's better if the default framerate has its own define to avoid
risking using different values in different places, and for readability.
While at it also remove some trivial comments about the framerates which
don't add much to the code anymore.

As reported by Peter Kovar, there's a potential risk of a division by
zero on calls to jpeg_set_qual() when quality is zero.
As quality can't be 0 or lower than that, add an extra clause to cover
this special case.

Store complete current mode (struct v4l2_pix_format) in struct gspca_dev
instead of separate pixfmt, width and height parameters.
This is a preparation for variable resolution support.

Write-only ioctls should have a const argument in the ioctl op.
Do this conversion for vidioc_s_jpegcomp.
Adding const for write-only ioctls was decided during the 2012 Media Workshop.
