I'll see if I can find a batter way to deal with this problem,
dell-laptop can detect the presence of an hardware switch.
dell-rbtn.ko has acpi method CRBT which returns if notebook has hw switch or
toggle key.
And rfkill implementation in dell-laptop.ko does not work correctly on
XPS machines. And because userspace implementation of smbios works fine,
I think that problem is in kernel driver rather in BIOS/firmware...
I was thinking about something such as the following, which should favor
the hardware slider when available. This should work if my assumption is
correct, that is the laptops with a working RBTN method are the ones
having problems.
Hm... wait! There are machines with HW slider and type is RBTN_TOGGLE?
I thought that all machines with HW slider has type RBTN_SLIDER and
others have RBTN_TOGGLE.
Yes, this is the problem I've been talking about ever since the work
on this driver started. AFAIK we don't know how to detect these laptops
(my XPS13 is one of them).
