Subject: [PATCH v3 2/3] PM: Make *_DEV_PM_OPS macros use __maybe_unused
Date: Thu, 16 Jul 2020 14:42:49 +0200 [thread overview]
Message-ID: <20200716124250.9829-2-paul@crapouillou.net> (raw)
In-Reply-To: <20200716124250.9829-1-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.
