[REGRESSION] probe with driver acpi-fan failed with error -22

[Laura Nao]

Hello,
                                                                         
We have identified a regression in the acpi-fan driver probe between 
v6.9-rc7 and v6.10-rc1 on some Intel Chromebooks in the Collabora LAVA 
lab.

For the Acer Chromebook Spin 514 (CP514-2H), the following error is 
reported in the logs:

[    0.651202] acpi-fan INTC1044:00: probe with driver acpi-fan failed with error -22

Similar errors are reported on other devices with fans compatible with 
the same driver.

On Acer Chromebox CXI4, ASUS Chromebook Flip C436FA and 
HP Chromebook x360 14 G1:

[    0.488001] acpi-fan INT3404:00: probe with driver acpi-fan failed with error -22

On ASUS Chromebook Vero 514 CBV514-1H:

[    1.168905] acpi-fan INTC1048:00: probe with driver acpi-fan failed with error -22

The issue is still present on next-20240529.

I'm sending this report to track the regression while a fix is 
identified. I'll investigate the issue/run a bisection and report back 
with the results.
                                     
This regression was discovered during some preliminary tests with the 
ACPI probe kselftest [1] in KernelCI. The config used was the upstream
x86_64 defconfig with a fragment applied on top [2].

Best,

Laura
