[RFC PATCH] interconnect: qcom: icc-rpm: Don't call __qcom_icc_set twice on the same node

[Konrad Dybcio]

Currently, when sync_state calls set(n, n) all the paths for setting
parameters on an icc node are called twice. Avoid that.

Fixes: 751f4d14cdb4 ("interconnect: icc-rpm: Set destination bandwidth as well as source bandwidth")

RFC comes from the fact that I *believe* this should be correct, but I'm
not entirely sure about it..
