When I test the irqchip code of Loongson, I read the related code of other
chips in drivers/irqchip and I find some potential resource leaks in the
error path, I think it is better to fix them. Additionally, do some code
cleanups about Loongson to make it more clean and readable.

Tiezhu Yang (7):
  irqchip: Fix potential resource leaks
  irqchip/loongson-htpic: Remove redundant kfree operation
  irqchip/loongson-htvec: Check return value of
    irq_domain_translate_onecell()
  irqchip/loongson-pch-pic: Check return value of
    irq_domain_translate_twocell()
  irqchip/loongson-pch-msi: Remove unneeded variable
  irqchip/loongson-htpic: Remove unneeded select of I8259
  dt-bindings: interrupt-controller: Fix typos in loongson,liointc.yaml
