Merge branch irq/misc-5.20 into irq/irqchip-next

* irq/misc-5.20:
  : .
  : Misc IRQ changes for 5.20:
  :
  : - Let irq_set_chip_handler_name_locked() take a const struct irq_chip *
  :
  : - Convert the ocelot irq_chip to being immutable (depends on the above)
  :
  : - Tidy-up the NOMAP irqdomain API variant
  :
  : - Teach action_show() to use for_each_action_of_desc()
  :
  : - Check ioremap() return value in the MIPS GIC driver
  :
  : - Move MMP driver init function declarations into the common .h
  :
  : - The obligatory typo fixes
  : .
  irqchip/mmp: Declare init functions in common header file
  irqchip/mips-gic: Check the return value of ioremap() in gic_of_init()
  genirq: Use for_each_action_of_desc in actions_show()
  irqdomain: Use hwirq_max instead of revmap_size for NOMAP domains
  irqdomain: Report irq number for NOMAP domains
  irqchip/gic-v3: Fix comment typo
  pinctrl: ocelot: Make irq_chip immutable
  genirq: Allow irq_set_chip_handler_name_locked() to take a const irq_chip
