One final pdx86 fix for Tablet Mode reporting regressions (which
 make the keyboard and touchpad unusable) on various Asus notebooks.
 
 This fix has been tested as a downstream patch in Fedora kernels for
 approx. 2 weeks with no problems being reported.

Merge tag 'platform-drivers-x86-v5.9-3' of git://git.kernel.org/pub/scm/linux/kernel/git/pdx86/platform-drivers-x86

Pull another x86 platform driver fix from Hans de Goede:
 "One final pdx86 fix for Tablet Mode reporting regressions (which make
  the keyboard and touchpad unusable) on various Asus notebooks.

  These regressions were caused by the asus-nb-wmi and the intel-vbtn
  drivers both receiving recent patches to start reporting Tablet Mode /
  to report it on more models.

  Due to a miscommunication between Andy and me, Andy's earlier pull-req
  only contained the fix for the intel-vbtn driver and not the fix for
  the asus-nb-wmi code.

  This fix has been tested as a downstream patch in Fedora kernels for
  approx two weeks with no problems being reported"
