** 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.
