Subject: [PATCH] interconnect: qcom: sdm845: Walk the list safely on node removal
Git-commit: b29b8113bb41285eb7ed55ce0c65017b5c0240f7
Patch-mainline: v5.5-rc2
References: git-fixes bnc#1151927 5.3.17
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")
