Subject: [PATCH v2 0/2] irqchip: xilinx: Switch to generic domain handler

Hi,

this series is based on cascade mode patch sent by Mubin
(https://lkml.org/lkml/2020/2/11/888 - v3 series).

The first patch is just fixing error patch. The second is converting microblaze
do_IRQ() to generic IRQ handler with appropriate changes in xilinx intc driver.

Also removes concurrent_irq global variable which wasn't wired
anywhere but it stores number of concurrent IRQs handled by one call. There
is option to get it back if needed but I haven't seen it in other archs
that's why I have removed it too.

Thanks,
Michal

Changes in v2:
- Merge generic irq multi handler(v1 2/3) and domain irq patch (v1 3/3) from together
- Add likely() suggested by Marc

Michal Simek (2):
  irqchip: xilinx: Fill error code when irq domain registration fails
  irqchip: xilinx: Enable generic irq multi handler
