Re: [PATCH v3 5/5] tty/serial: Add Spreadtrum sc9836-uart driver support

Yes, I saw this way in other serial drivers.
But, if then, there are two questions for me:
1. Why did some serial drivers need an UN_SHARED irq?
2. How can we choose a right way?

If your hardware can support sharing an IRQ then shared is the right way
- along with the test Arnd suggested. Some hardware lacks the needed
facilities to handle shared interrupt.
