From: Hans de Goede <redacted> [ Upstream commit a22e3803f2a4d947ff0083a9448a169269ea0f62 ] Teclast X89 tablets come in 2 versions, with Windows pre-installed and with Android pre-installed. These 2 versions have different DMI strings. Add a match for the DMI strings used by the Android version BIOS. Note the Android version BIOS has a bug in the DSDT where no IRQ is provided, so for the touchscreen to work a DSDT override fixing this is necessary as well.
