After a provider\nunbind/rebind cycle (deferred-probe replay during early boot, real\nmodule unload of a clk driver that owns GDSCs, or an OF-overlay tear-\ndown) the next gdsc_init() will end up trying to re-register a name\nthat is still in the list and pm_genpd_init() returns -EEXIST.\n\nWhile we are here, flip the order so the consumer-facing OF provider\nentry is the first thing removed -- otherwise a fresh\nof_genpd_get_from_provider() call racing with the teardown could\nattach to a domain that is mid-removal.\n\nIterate the scs[] array and pm_genpd_remove() each registered domain\nafter the subdomain links are torn down. The regulators stay devm-\nmanaged (devm_regulator_get_optional() in gdsc_register()), so the\nrelease happens automatically when the underlying device is unbound;\njust the genpd accounting needs to be undone explicitly.","state":0,"publishedAt":"2026-09-17T16:11:43.421+00:00","modifiedAt":"2026-10-19T09:06:17.744+00:00","affected":[{"ecosystem":"Vendor
