X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=90438926e807bca4f80237f436bc7d904151fc2b;p=openwrt%2Fstaging%2Fblogic.git

[media] soc-camera: don't attach the client to the host during probing

During client probing we only have to turn on the host's clock, no need to
actually attach the client to the host.
