Subject: Do not set IDN2_NFC_INPUT explicitly
X-Git-Tag: v9.13.3~124^2~1
X-Git-Url: http://git.ipfire.org/gitweb/?a=commitdiff_plain;h=bf6efbc9a99a102232f69a83701c2793381ef91c;p=thirdparty%2Fbind9.git

Do not set IDN2_NFC_INPUT explicitly

IDN2_NFC_INPUT is always set implicitly by idn2_to_ascii_lz(), so there
is no need to set it explicitly.
