Subject: [PATCH 05/10] serial: stm32: Use __maybe_unused instead of #if CONFIG_PM_SLEEP
Date: Tue, 4 Jun 2019 10:55:14 +0200 [thread overview]
Message-ID: <1559638519-6128-6-git-send-email-erwan.leray@st.com> (raw)
In-Reply-To: <1559638519-6128-1-git-send-email-erwan.leray@st.com>
Use __maybe_unused for power management related functionsinstead of
#if CONFIG_PM_SLEEP to simply the code.
fixes: 270e5a74fe4c ("serial: stm32: add wakeup mechanism")
