Subject: [PATCH] mailbox: tegra-hsp: mark PM functions as __maybe_unused
Date: Tue,  8 Jan 2019 15:37:13 +0100
Message-ID: <20190108143713.15120-1-anders.roxell@linaro.org> (raw)

Without CONFIG_PM_SLEEP, we get annoying warnings about unused
functions:

drivers/mailbox/tegra-hsp.c:782:12: warning: ‘tegra_hsp_resume’ defined but not used [-Wunused-function]
 static int tegra_hsp_resume(struct device *dev)
            ^~~~~~~~~~~~~~~~

Mark them as __maybe_unused to shut up the warning and silently drop the
functions without having to add ugly #ifdefs.

Fixes: 9a63f0f40599 ("mailbox: tegra-hsp: Add suspend/resume support")
Signed-off-by: Anders Roxell <anders.roxell@linaro.org>
