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"
