can: m_can: mark runtime-PM handlers as __maybe_unused
Building without CONFIG_PM results in a harmless warning: drivers/net/can/m_can/m_can.c:1763:12: error: 'm_can_runtime_resume' defined but not used [-Werror=unused-function] drivers/net/can/m_can/m_can.c:1752:12: error: 'm_can_runtime_suspend' defined but not used [-Werror=unused-function] Marking the functions as __maybe_unused lets the compiler silently drop them instead. Fixes: cdf8259d6573 ("can: m_can: Add PM Support") Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de>
