Shawn Guo d511caa25d cpuidle: psci: Iterate backwards over list in psci_pd_remove() ... commit 6b0313c2fa3d2cf991c9ffef6fae6e7ef592ce6d upstream. In case that psci_pd_init_topology() fails for some reason, psci_pd_remove() will be responsible for deleting provider and removing genpd from psci_pd_providers list. There will be a failure when removing the cluster PD, because the cpu (child) PDs haven't been removed.
