This does not cover all drivers which depend on ACPI_WMI; and in
for-next there is a new UV_SYSFS Kconfig symbol in the middle of
the block which you are surrounding with if ACPI_WMI .. endif
and that new Kconfig symbol does not depend on ACPI_WMI.

Admittedly I should have payed more attention when the UV_SYSFS
symbol was merged, but atm there is no real ordering in the
Kconfig symbols.

Personally I think having e.g. the non WMI and WMI based drivers
for say Asus laptops together makes more sense then grouping
the WMI drivers together.

I'm tempted to add a commit to for-next which just sorts everything
alphabetically. Doing so might cause conflicts, so doing it
close (but not too close) to the merge window seems like a good
time to do this.

What do you think (about just sorting all the symbols alphabetically) ?

Regards,

Hans
