Bug Description

[SRU Justification]

[Impact]
On Hewlett-Packard x360 310 G2 convertible laptop,
/sys/devices/platform/hp-wmi/tablet cannot report its current mode:

  # cat /sys/devices/platform/hp-wmi/tablet
  cat: /sys/devices/platform/hp-wmi/tablet: Invalid argument

[Fix]
Commit 133b2acee387 ("platform/x86: hp-wmi: Make buffer for HPWMI_FEATURE2_QUERY
128 bytes") to be cherry-picked to kernels <= v5.4.6.

[Test Case]
Just run `cat /sys/devices/platform/hp-wmi/tablet`.

[Regression Potential]
Low. This affects only HP systems with such buffer length check that
should be fixed.

========== original bug description ==========

# cat /sys/devices/platform/hp-wmi/tablet
cat: /sys/devices/platform/hp-wmi/tablet: Invalid argument

Ubuntu 18.04.3 LTS

Thanks for the rapid fix. Can't test the PPA as I'm on 5.3.0-26-generic in Bionic for which it has no upgrade candidate.

Just add that PPA and update its series to bionic and run apt update again.

The PPA is added and its series is bionic. I have 5.3.0-26-generic installed, the PPA offers 4.15.0-76.86+lp1860940 for bionic and 5.3.0-29.31+lp1860940 for eoan, what am I missing?

Errr, sorry, I mean update its series to eoan, so that you may install 5.3.0-29.31+lp1860940 for eoan on Bionic.
