Subject: PM / Domains: Fix unsafe iteration over modified list of domains
From: Krzysztof Kozlowski <[email protected]>
commit a7e2d1bce4c1db471f1cbc0c4666a3112bbf0994 upstream.
of_genpd_remove_last() iterates over list of domains and removes matching element thus it has to use safe version of list iteration.
