This causes the following error to be logged and the slot to not work: [ 10.572113] sdhci-pci 0000:00:12.0: failed to setup card detect gpio Add a DMI quirk table for providing gpiod_lookup_tables with manually provided CD GPIO info and use this DMI table to provide the CD GPIO info on this tablet. This fixes the microsd-slot not working.
