This tablet has an incorrect acpi identifier, which is why it is trying to load the RT5640 driver instead of the RT5762 driver. The RT5640 driver, on the other hand, checks the hardware ID, so no drivers are loaded during boot. This fix resolves to load the RT5672 driver on this tablet during boot. It also provides the correct IO configuration, like the jack detect mode 3, for 1.8V pullup. I would like to thank Pierre-Louis Bossart for helping with this patch.
