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" * tag 'platform-drivers-x86-v5.9-3' of git://git.kernel.org/pub/scm/linux/kernel/git/pdx86/platform-drivers-x86: platform/x86: asus-wmi: Fix SW_TABLET_MODE always reporting 1 on many different models
