[PATCH 00/11] PM / Domains: Fixup error paths with dev_pm_domain_attach()

From: Ulf Hansson
Date: Thu Apr 26 2018 - 04:53:27 EST


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.

Ulf Hansson (11):
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()
driver core: Respect all error codes from dev_pm_domain_attach()
i2c: Respect all error codes from dev_pm_domain_attach()
mmc: sdio: Respect all error codes from dev_pm_domain_attach()
soundwire: Respect all error codes from dev_pm_domain_attach()
spi: Respect all error codes from dev_pm_domain_attach()
