ACPI: AC: Quirk GK45 to skip reading _PSR
[ Upstream commit
3d730ee686800d71ecc5c3cb8460dcdcdeaf38a3 ]
Let GK45 not go into BIOS for determining the AC power state.
The BIOS wrongly returns 0, so hardcode the power state to 1.
The mini PC GK45 by Besstar Tech Lld. (aka Kodlix) just runs
off AC. It does not include any batteries. Nevertheless BIOS
reports AC off:
root@kodlix:/usr/src/linux# cat /sys/class/power_supply/ADP1/online
0
root@kodlix:/usr/src/linux# modprobe acpi_dbg
root@kodlix:/usr/src/linux# tools/power/acpi/acpidbg
