Subject: Fix return type of vde_recv() as well.
X-Git-Tag: release-1.0.18~2
X-Git-Url: https://www.tinc-vpn.org/git/browse?p=tinc;a=commitdiff_plain;h=f71ce341800739c7cdee01d7cf025e7492da22ac;ds=sidebyside

Fix return type of vde_recv() as well.

In this case it is not really necessary as the conversion to int will already
take care of ensuring the return value is treated as signed.
