Subject: rpmsg: Only invoke announce_create for rpdev with endpoints
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=7586516ca043d55ed1ca563df72bc216c948cad4;p=openwrt%2Fstaging%2Fblogic.git

rpmsg: Only invoke announce_create for rpdev with endpoints

For special rpmsg devices without a primary endpoint there is nothing to
announce so don't call the backend announce create function if we didn't
create an endpoint.
