   4 Subject: thermal: qcom: tsens-8916: mark PM functions __maybe_unused
   5
   6 The newly added tsens-8916 driver produces warnings when CONFIG_PM
   7 is disabled:
   8
   9 drivers/thermal/qcom/tsens.c:53:12: error: 'tsens_resume' defined but not used [-Werror=unused-function]
  10  static int tsens_resume(struct device *dev)
  11             ^~~~~~~~~~~~
  12 drivers/thermal/qcom/tsens.c:43:12: error: 'tsens_suspend' defined but not used [-Werror=unused-function]
  13  static int tsens_suspend(struct device *dev)
  14             ^~~~~~~~~~~~~
  15
  16 This marks both functions __maybe_unused to let the compiler
  17 know that they might be used in other configurations, without
  18 adding ugly #ifdef logic.
