This patchset enabled the recently added ->attach_dev() callback to return an error code. Typically these callbacks will fetch some PM resourses, like clocks through a clk_get() which may fail. To be able to handle the errors we need to return an error code. Do note, the buses which invokes dev_pm_domain_attach() are already handling -EPROBE_DEFER, which means the ->attach_dev() callbacks may also return this if needed.
