[SRU][B/E/OEM-B/OEM-OSP1-B][PATCH 0/1] Fix hp_wmi HPWMI_FEATURE2_QUERY failure

[You-Sheng Yang]

BugLink: https://bugs.launchpad.net/bugs/1860940

[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.
