[PATCH] thermal: qcom: tsens-8916: mark PM functions __maybe_unused

From: Arnd Bergmann
Date: Mon Jul 04 2016 - 09:10:30 EST


The newly added tsens-8916 driver produces warnings when CONFIG_PM
is disabled:

drivers/thermal/qcom/tsens.c:53:12: error: 'tsens_resume' defined but not used [-Werror=unused-function]
static int tsens_resume(struct device *dev)
^~~~~~~~~~~~
drivers/thermal/qcom/tsens.c:43:12: error: 'tsens_suspend' defined but not used [-Werror=unused-function]
static int tsens_suspend(struct device *dev)
^~~~~~~~~~~~~

This marks both functions __maybe_unused to let the compiler
know that they might be used in other configurations, without
adding ugly #ifdef logic.
