** Description changed:
+ === SRU Justification ===
+ [Impact]
+ [ 406.165461] hid-sensor-hub 001F:8086:22D8.0002: hid_field_extract() called
with n (192) > 32! (kworker/5:1)
+
+ [Fix]
+ Let HID core allow longer input report length.
+
+ [Test]
+ User confirmed the fix works.
+
+ [Regression Potential]
+ Low. Longer input report length is now considered valid, shorter input
+ report length doesn't get touched.
+
+ === Original Bug Report ===
+
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.
** Also affects: linux (Ubuntu Disco)
