[ Upstream commit 7f45621c14a209b986cd636447bb53b7f6f881c3 ]
Unfortunately we have been unable to find a reliable way to detect if and how SW_TABLET_MODE reporting is supported, so we are relying on DMI quirks for this.
Add a module-option to specify the SW_TABLET_MODE method so that this can be easily tested without needing to rebuild the kernel.
