+Subject: thermal: qcom: tsens-8916: mark PM functions __maybe_unused
+
+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.
