The IRQ is masked while the primary is handler is invoked independently of IRQF_ONESHOT. With IRQF_ONESHOT the core code will not force-thread the interrupt and this is probably not intended. I *assume* that the original author copied the IRQ registration from another driver which passed a primary and secondary handler and removed the secondary handler but keeping the ONESHOT flag. Remove IRQF_ONESHOT.
