           Summary: Writing to dgpu_disable always produce Input/Output
                    error

output of journalctl and lspci

Device Info:

Asus Zephyrus G14 GA402RJ
Latest BIOS
Arch_x86_64
Kernel 6.6.10-arch1
Minimal arch install

ISSUE: Writing 0 to /sys/devices/platform/asus-nb-wmi/dgpu_disable, will always
produce an Input/Output error(echo 1 | tee ../dgpu_disable). While writing 1 to
it seems fine. There's also an issue of system crash and reboot after echo 1 |
tee ../pci/rescan. 

Steps to Reproduce:

echo 1 | tee ../remove(dgpu path)
echo 1 | tee /sys/devices/platform/asus-nb-wmi/dgpu_disable
echo 0 | tee /sys/devices/platform/asus-nb-wmi/dgpu_disable
echo 1 | tee /sys/bus/pci/rescan

Observations:

Did the above steps 10 times, everytime it produced an Input/Output error and
everytime system crashed and rebooted, during pci rescan.
journalctl -p 3 showed an ACPI error after writing 0 to dgpu_disable.

journalctl -p 3, lspci are attached.
