Hrm, I went looking to see if I could help resolve, but I have to admit,
at first glance I don't get it. The commit diff:

The increase from 128 to 256 should not create a scenario where the bug
can exist. If it was originally below 128 and not throwing an error,
then it should be below 256.

Title:
hid-sensor-hub spamming dmesg in 4.20
Status in linux package in Ubuntu:
Confirmed
Bug description:
Dmesg is a constant barrage of the same error:
```
[ 406.165461] hid-sensor-hub 001F:8086:22D8.0002: hid_field_extract() called
with n (192) > 32! (kworker/5:1)
```
This does not occur in 4.19 but does occur in all mainline 4.20
releases including 4.20.13 (linux-image-unsigned-4.20.13-042013).
Tested with both Ubuntu's included libinput 1.10 and an updated
libinput 1.12.
Hardware (from lspci) includes a synaptic touchpad. Having the xorg
synaptic driver installed makes no difference.
