Subject: PM / runtime: Fix handling of suppliers with disabled runtime PM

From: "Rafael J. Wysocki" <[email protected]>

[ Upstream commit 31eb7431805493e10f4731f366cf4d4e3e952035 ]

Prevent rpm_get_suppliers() from returning an error code if runtime PM is disabled for one or more of the supplier devices it wants to runtime-resume, so as to make runtime PM work for devices with links to suppliers that don't use runtime PM (such links may be created during device enumeration even before it is known whether or not runtime PM will be enabled for the devices in question, for example).
