Subject: [PATCH v5 00/14] irqchip: Fix potential resource leaks

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.

v2:
  - Split the first patch into a new patch series which
    includes small patches and add "Fixes" tag
  - Use "goto" label to handle error path in some patches

v3:
  - Add missed variable "ret" in the patch #5 and #13

v4:
  - Modify the commit message of each patch suggested by Markus Elfring
  - Make "irq_domain_remove(root_domain)" under CONFIG_SMP in patch #3
  - Add a return statement before goto label in patch #4

v5:
  - Modify the commit messages and do some code cleanups
