[PATCH] PM / Domains: Do not print PM domain add error message if EPROBE_DEFER
STALE3591d
From: Geert Uytterhoeven <geert+renesas@glider.be>

Also in:
linux-renesas-soc
Subsystem:
driver core, kobjects, debugfs and sysfs, hibernation (aka software suspend, aka swsusp), power management core, suspend to ram, the rest · Maintainers:
Greg Kroah-Hartman, "Rafael J. Wysocki", Danilo Krummrich, Linus Torvalds
EPROBE_DEFER is not an error, hence printing an error message like
renesas_irqc e61c0000.interrupt-controller: failed to add to PM domain always-on: -517
may confuse the user.
Suppress the error message in case of EPROBE_DEFER to fix this.
