+ * Selftest allows for the testing of the mechanical and electrical
+ * portions of the sensors. When the selftest is activated, the
+ * electronics cause the sensors to be actuated and produce an output
+ * signal. The output signal is used to observe the selftest response.
+ * When the selftest response exceeds the min/max values,
+ * the part is deemed to have failed selftest.

+ * Input Parameters:
+ * lower - The instance of lower half sensor driver.
+ * arg - The parameters associated with selftest.
+ *
+ * Returned Value:
+ * Zero (OK) on success; a negated errno value on failure.
