Subject[PATCH] can: m_can: mark runtime-PM handlers as __maybe_unused
Date
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")
