Subject[PATCH v2 01/20] rpmsg: glink: Rename glink_rpm_xx functions to qcom_glink_xx
Date
From: Bjorn Andersson <bjorn.andersson@linaro.org>

Renaming the glink_rpm_xx functions and structs to qcom_glink_xx
equivalents helps to reuse the core glink protocol while adding
support for smem based glink transport in the later patches.
