Subject: [PATCH] i2c: stm32f7: avoid ifdef CONFIG_PM_SLEEP for pm callbacks
Date: Fri, 12 Mar 2021 12:53:27 +0100 [thread overview]
Message-ID: <1615550007-10927-1-git-send-email-alain.volmat@foss.st.com> (raw)
Avoid CONFIG_PM preprocessor check for pm suspend/resume
callbacks and identify the functions with __maybe_unused.
