Broken GPIO IRQ mappings in 5.18-rc2

Hi,
I noticed on a variety of machines that power button wasn't working anymore starting with 5.18-rc2.
In digging deeper, I notice that a new error is introduced as well during bootup:
[ 0.688318] amd_gpio AMDI0030:00: Failed to translate GPIO pin 0x0000 to IRQ, err -517
[ 0.688337] amd_gpio AMDI0030:00: Failed to translate GPIO pin 0x002C to IRQ, err -517
[ 0.688348] amd_gpio AMDI0030:00: Failed to translate GPIO pin 0x003D to IRQ, err -517
[ 0.688359] amd_gpio AMDI0030:00: Failed to translate GPIO pin 0x003E to IRQ, err -517
[ 0.688369] amd_gpio AMDI0030:00: Failed to translate GPIO pin 0x003A to IRQ, err -517
[ 0.688379] amd_gpio AMDI0030:00: Failed to translate GPIO pin 0x003B to IRQ, err -517
[ 0.688389] amd_gpio AMDI0030:00: Failed to translate GPIO pin 0x0002 to IRQ, err -517
[ 0.688399] amd_gpio AMDI0030:00: Failed to translate GPIO pin 0x0011 to IRQ, err -517
[ 0.688410] amd_gpio AMDI0030:00: Failed to translate GPIO pin 0x0012 to IRQ, err -517
[ 0.688420] amd_gpio AMDI0030:00: Failed to translate GPIO pin 0x0007 to IRQ, err -517
It looks like IRQs aren't getting assigned to the GPIO pins anymore and instead showing this deferred probing message in 5.18-rc2.
I bisected and confirmed it's caused by
commit 5467801f1fcbdc46bc7298a84dbf3ca1ff2a7320 ("gpio: Restrict usage of GPIO chip irq members before initialization")
I don't see that probing ever gets a chance to run again though as it just shows the dev_err and returns AE_OK for the
function that walks _AEI (acpi_gpiochip_alloc_event).
FYI - I'm CC'ing stable because this commit went to stable too.
Thanks,
