bryanodonoghue: in eb73facec2c2 I see you added `vfe->genpd_link = NULL` to `pm_domain_off`. this would be fine if `vfe_put` was the only function to call it since it keeps track of `power_count` and ensures every `pm_domain_off` is matched with a previous `pm_domain_on`, but `ispif_reset` skips that and calls `pm_domain_put` directly, then when `vfe_put` is called it calls `pm_domain_put` again causing null pointer dereference.
