The driver neglects to check the result of platform_get_irq()'s call and blithely passes the negative error codes to request_threaded_irq() (which takes *unsigned* IRQ #), causing it to fail with -EINVAL, overriding an original error code. Stop calling request_threaded_irq() with the invalid IRQ #s.
