Subject: virCapabilitiesHostNUMAUnref: Accept NULL
X-Git-Tag: v6.0.0-rc1~212
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=599f9c73d45369e2087be8ead53df8710d0f88dd;p=thirdparty%2Flibvirt.git

virCapabilitiesHostNUMAUnref: Accept NULL

Fortunately, this is not causing any problems now because glib
does this check for us when calling this function via attribute
cleanup. But in a future commit we will explicitly call this
function over a struct member that might be NULL.
