[PATCH 3/4] rpmsg: glink: Integrate glink_ssr in qcom_glink
From: Bjorn Andersson
Date: Wed Apr 22 2020 - 20:38:20 EST
In all but the very special case of a system with _only_ glink_rpm,
GLINK is dependent on glink_ssr, so move it to rpmsg and combine it with
qcom_glink_native in the new qcom_glink kernel module.
