Subject: hostip: avoid unused parameter error in Curl_resolv_check
X-Git-Tag: curl-7_82_0~24
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8a1fa3b364b9db52cf3e8d843ac1e749890985e6;p=thirdparty%2Fcurl.git

hostip: avoid unused parameter error in Curl_resolv_check

When built without DNS-over-HTTP and without asynchronous resolvers,
neither the dns nor the data parameters are used.

That is Curl_resolv_check appears to call
Curl_resolver_is_resolved(data, dns). But,
with CURL_DISABLE_DOH without CURLRES_ASYNCH, the call is actually
elided via a macro definition.

This fix resolves the resultant: "unused parameter 'data'" error.

Closes #8505
