kernel-doc: Make it compatible with Perl versions below 5.12 again
Changeset 4d73270192ec('scripts/kernel-doc: Replacing highlights hash by an array') broke compatibility of the kernel-doc script with older versions of perl by using "keys ARRAY" syntax with is available only on Perl 5.12 or newer, according with: http://perldoc.perl.org/functions/keys.html Restore backward compatibility by replacing "foreach my $k (keys ARRAY)" by a C-like variant: "for (my $k = 0; $k < !ARRAY; $k++)" Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com> Signed-off-by: Jonathan Corbet <corbet@lwn.net>
