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 $_;
}

"program_info_length" is user controlled and can go up to 4095. The
operand[] array has 509 bytes so we need to add a limit here to prevent
buffer overflows.
The " - 4" in the limit check is because we have 4 bytes more data to
add after the memcpy().
[mchehab@osg.samsung.com: as I merged the version 1 of the patch, I needed
to rebase to apply just the differences between v1 and v2]
