SPI device not detected

[jacklu333333]

Hi, I am using Asus Flip S UX370UAF with ArchLinux. When I tried to list available devices, there were none.
However with cmd
cat /sys/bus/acpi/devices/*/path | grep "\.SPI\|\.FPNT"

I have output

\_SB_.PCI0.SPI0
\_SB_.PCI0.SPI1.FPNT
\_SB_.PCI0.SPI0.SPBA
\_SB_.PCI0.SPI1

Is there any way I can modify the code to get it to work?

Thanks in advance.
