Subject: [PATCH 4.17 094/324] arm64: dts: msm8916: fix Coresight ETF graph connections

4.17-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Rob Herring <robh@...nel.org>

[ Upstream commit 6b4154a655a258c67bcfabbd4c3a06637e74ebcd ]

The ETF input should be connected to the funnel output, and the ETF
output should be connected to the replicator input. The labels are wrong
and these got swapped:

Warning (graph_endpoint): /soc/funnel@...000/ports/port@...ndpoint: graph connection to node '/soc/etf@...000/ports/port@...ndpoint' is not bidirectional
Warning (graph_endpoint): /soc/replicator@...000/ports/port@...ndpoint: graph connection to node '/soc/etf@...000/ports/port@...ndpoint' is not bidirectional
