--------------------------------

commit 06fb4ecf upstream.

Commit 5467801f ("gpio: Restrict usage of GPIO chip irq members
before initialization") attempted to fix a race condition that lead to a
NULL pointer, but in the process caused a regression for _AEI/_EVT
declared GPIOs.

This manifests in messages showing deferred probing while trying to
allocate IRQs like so:

  amd_gpio AMDI0030:00: Failed to translate GPIO pin 0x0000 to IRQ, err -517
  amd_gpio AMDI0030:00: Failed to translate GPIO pin 0x002C to IRQ, err -517
  amd_gpio AMDI0030:00: Failed to translate GPIO pin 0x003D to IRQ, err -517
  [ .. more of the same .. ]

The code for walking _AEI doesn't handle deferred probing and so this
leads to non-functional GPIO interrupts.

Fix this issue by moving the call to `acpi_gpiochip_request_interrupts`
to occur after gc->irc.initialized is set.
