Bug Description

[Impact]
  Add new palm sensor supports to Lenovo Thinkpad systems

[Fix]
  thinkpad_acpi is updated to check palm sensor presence and its events

[Test]
  Tested on Thinkpad systems

[Where problems could occur]
  Low risks. Only thinkpad systems are affected. Also thinkpad systems without palm sensor and without TP_HKEY_EV_PALM_DETECTED & TP_HKEY_EV_PALM_UNDETECTED events won't be affected either.

  There can an issue as discussed in commit log of "thinkpad_acpi: Add palm sensor support"

    Note: On some platforms, because of an issue in the HW implementation,
    the palm sensor presence may be incorrectly advertised as always
    enabled even if a palm sensor is not present. The palm sensor is
    intended for WWAN transmission power control and should be available
    and correct on all WWAN enabled systems. It is not recommended to use
    this interface for other use cases.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-focal' to 'verification-done-focal'. If the problem still exists, change the tag 'verification-needed-focal' to 'verification-failed-focal'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
