Subject: scripts/metadata.pm: avoid adding dup names in provides list
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=204081670b914795a494929777f09807b15f70f4;p=openwrt%2Fstaging%2Fnbd.git

scripts/metadata.pm: avoid adding dup names in provides list

The need arises from building Open vSwitch kernel datapath modules, e.g.

 - kmod-openvswitch from Linux upstream
 - kmod-openvswitch-intree from openvswitch source code

where both provides virtual package "kmod-openvswitch" for userspace
packages to select and depend on
