Subject: virQEMUCapsProcessStringFlags: Don't require 'nvalues'
X-Git-Tag: v7.5.0-rc1~77
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b20ef5e6de53e881740de9fe7ab1a02c2517b217;p=thirdparty%2Flibvirt.git

virQEMUCapsProcessStringFlags: Don't require 'nvalues'

All callers pass in NULL-terminated string lists. Remove the 'nvalues'
argument and fix all callers.
