While I was on working adding support for multiple PM domains to genpd, I
stumbled over several problems in the error path related to
dev_pm_domain_attach(). Hence, I decided to fix these problems first, which is
what this series intends to address.

There first patch is material for stable, as it fixes a real bug in genpd,
while the rest may be considered as improvement of the error paths when devices
fails to be attached to their PM domains.

I am seeking acks from subsystem maintainers and suggest with funnel the hole
series through Rafael's linux-pm tree, unless there are objections to that of
course.

  PM / Domains: Fix error path during attach in genpd
  PM / Domains: Drop comment in genpd about legacy Samsung DT binding
  PM / Domains: Drop redundant code in genpd while attaching devices
  PM / Domains: Check for existing PM domain in dev_pm_domain_attach()
  PM / Domains: Allow a better error handling of dev_pm_domain_attach()
  amba: Respect all error codes from dev_pm_domain_attach()
