Subject: ui/vnc: fix handling of VNC_FEATURE_XVP
X-Git-Tag: v8.1.2~40
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=3b86b92bfbbebbc8f6801588dafce7d76c1782d9;p=thirdparty%2Fqemu.git

ui/vnc: fix handling of VNC_FEATURE_XVP

VNC_FEATURE_XVP was not shifted left before adding it to vs->features,
so it was never enabled; but it was also checked the wrong way with
a logical AND instead of vnc_has_feature.  Fix both places.
