[PATCH 2/4] interconnect: qcom: sdm845: Walk the list safely on node removal
From: Georgi Djakov
Date: Thu Dec 12 2019 - 02:53:58 EST
As we will remove items off the list using list_del(), we need to use the
safe version of list_for_each_entry().
Fixes: b5d2f741077a ("interconnect: qcom: Add sdm845 interconnect provider driver")
