Pull rpmsg updates from Bjorn Andersson:
"The remove functions of the Qualcomm SMD and GLINK RPM platform
drivers are transitioned to the new void returning prototype. Likewise
is qcom_smd_unregister_edge() transitioned to void, as it
unconditionally returned 0.
An assumption about the ordering of the intent request acknowledgement
and advertisement of a new intent in the GLINK implementation is
corrected. Faulty error handling is corrected is improved in the TX
path, and duplicated code, in the same path, is cleaned up"
