SYNOPSIS
       int request_any_context_irq(unsigned int irq, irq_handler_t handler, unsigned long flags,
                                   const char * name, void * dev_id);

ARGUMENTS
       irq
           Interrupt line to allocate

DESCRIPTION
       This call allocates interrupt resources and enables the interrupt line and IRQ handling.
       It selects either a hardirq or threaded handling method depending on the context.

       On failure, it returns a negative value. On success, it returns either IRQC_IS_HARDIRQ or
       IRQC_IS_NESTED.
