The driver currently sets the handler data and the chained handler in two separate steps. This creates a theoretical race window where an interrupt could fire after the handler is set but before the data is assigned, leading to a NULL pointer dereference. Replace the two calls with irq_set_chained_handler_and_data() to set both the handler and its data atomically under the irq_desc->lock.
