Re: [PATCH 0/3] Dell Airplane Mode Switch driver

[Alex Hung]

HI Darren and Pali,

It was great that we had a lot of discussion but it seems Dell BIOS
implementation varies from one series to another. Both work looks good
either one is fine with me.

But I think I can do a little more: I am collecting a number of
systems to try out these patches. This should help us determine which
one work better and probably we can integrate.

Currently I have found four systems (including two Latitude, an
Inspiron and a XPS with working method(ARBT) that Gabriele suggested).
I can get other, ex. a Vostro, if needed.

I will test dell-wireless.c with Gabriele's suggestion and Pali's
dell-rbtn.c (btw, will there be updates?). However, I will need a few
days to do the comparison.

Any suggested test cases?

Cheers,
Alex Hung
