Subject: [PATCH 0/2] soc: rockchip: fix probe error path in power-domain driver

A recent change to generic power-domains revealed that the rockchip
driver cannot safely fail it's probe. Also pm_genpd_init creates a
situation where a probe error leads to the generic power-domains
accessing already freed data.

The reason for us finding this issue (holes in power-domain lists), will
get fixed in the generic power-domains, but the fixes below will only
work after the newly added genpd-removal code got merged.

Therefore I hope to remember to send the two patches below as fix after
4.9-rc1.

Alternatively Rafael could include them into his branch directly.

  soc: rockchip: power-domain: use pm_genpd_remove in error cleanup

  soc: rockchip: power-domain: Handle errors from
    of_genpd_add_provider_onecell
