4.19-stable review patch. If anyone has any objections, please let me know. ------------------ From: Bjorn Andersson <quic_bjorande@xxxxxxxxxxx> [ Upstream commit 4e816d0318fdfe8932da80dbf04ba318b13e4b3a ] The upstream GLINK driver was first introduced to communicate with the RPM on MSM8996, presumably as an artifact from that era the command defines was prefixed RPM_CMD, while they actually are GLINK_CMDs. Let's rename these, to keep things tidy. No functional change.
