Subject: [PATCH] interconnect: qcom: rpm: drop bogus pm domain attach
References: bsc#1012628
Patch-mainline: 6.3.2
Git-commit: 72b2720c18ecde92e6a36c4ac897dd5848e3f379
[ Upstream commit 72b2720c18ecde92e6a36c4ac897dd5848e3f379 ]
Any power domain would already have been attached by the platform bus
code so drop the bogus power domain attach which always succeeds from
probe.
This effectively reverts commit 7de109c0abe9 ("interconnect: icc-rpm:
Add support for bus power domain").
Fixes: 7de109c0abe9 ("interconnect: icc-rpm: Add support for bus power domain")
