Subject: [RFC PATCH 2/3] PM: Make *_DEV_PM_OPS macros use __maybe_unused
Date: Tue, 11 Feb 2020 13:03:20 -0300	[thread overview]
Message-ID: <20200211160321.22124-3-paul@crapouillou.net> (raw)
In-Reply-To: <20200211160321.22124-1-paul@crapouillou.net>

This way, when the dev_pm_ops instance is not referenced anywhere, it
will simply be dropped by the compiler without a warning.
