[Regression] 6.8 - i2c_hid_acpi: probe of i2c-XXX0001:00 failed with error -110

I'm currently developing on the OrangePi Neo-01, which ships with two similar touchpads using the Synaptics driver. On 6.7.10 those two devices get detected normally. On 6.8.1 it seems to error out.

I either get none, or at best only one of those two devices.

i2c_hid_acpi: probe of i2c-XXX0001:00 failed with error -110 i2c_hid_acpi: probe of i2c-XXX0002:00 failed with error -110

what would be the best way to debug this?
