A user complained that the lg-laptop driver does not work on 2024
models like the LG Gram 16Z90S-G.AD7BF. The underlying reason turned
out to be that the ACPI methods used by this driver where not mapped
under \XINI, but instead under \_SB.XINI. Those ACPI methods are
associated with the LGEX0820 ACPI device, which was not used by this
driver until now.
The first three patches move the airplane mode hotkey handling out
of lg-laptop and into the wireless-hotkey driver. This necessary
because the airplane mode hotkey is handled by a different ACPI
device (LGEX0815).
The last patch finally fixes the underlying issue and uses the
LGEX0820 ACPI device to find theWMAB/WMBB ACPI methods.
The modified drivers where tested by the user which created the
bug report and appear to work without issues.
