Subject: codegen: Fix return-type for cancelled async creation methods of classes
X-Git-Tag: 0.38.6~5
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=fc2b0ea03050760ede60bc56971081a9ce9a23b4;p=thirdparty%2Fvala.git

codegen: Fix return-type for cancelled async creation methods of classes

While gcc just puts out a warning clang actually fails due to
-Werror=return-type.
