/**
 * @brief Run a function in interrupt context
 *
 * This function synchronously runs the provided function in interrupt
 * context, passing in the supplied device. Useful for test code
 * which needs to show that kernel objects work correctly in interrupt
 * context.
 *
 * Additionally, when CONFIG_IRQ_OFFLOAD_NESTED is set by the
 * architecture, this routine works to synchronously invoke a nested
 * interrupt when called from an ISR context (i.e. when k_is_in_isr()
 * is true).  Note that not all platforms will have hardware support
 * for this capability, and even on those some interrupts may be
 * running at unpreemptible priorities.
 *
 * @param routine The function to run
 * @param parameter Argument to pass to the function when it is run as an
 * interrupt
