From: Laurent Pinchart <[email protected]> The driver claims it needs to register an interrupt handler too early for request_irq(). This might have been true in the past, but the only meaningful difference between request_irq() and setup_irq() today is an additional kzalloc() call in request_irq(). As the driver calls kmalloc() itself we know that the slab allocator is available, we can thus switch to request_irq().
