[PATCH] platform/x86/asus-nb-wmi.c: Add X45U quirk

[Marcos Paulo de Souza]

Without this patch, the Asus X45U wireless card can't be turned
on (hard-blocked), but after a suspend/resume it just starts working.

Following this bug report[1], there are other cases like this one, but
this Asus is the only model that I can test.

<formletter>

This is not the correct way to submit patches for inclusion in the
stable kernel tree.  Please read Documentation/stable_kernel_rules.txt
for how to do this properly.

Thanks Marcos,

As Greg pointed out, if you want this to go back to stable, you need to
add the Cc: stable tag below your Signed-off-by. I also ask that you
attempt to apply this yourself before sending it back to stable. Does it
apply to 4.8? 4.1? 3.18? How far back do you want to see this backported
to stable?

Sorry, first time sending a patch to stable. I'm cloning stable here to check if this patch applies smoothly on 4.8 and 4.1, and then resend it to stable. This patch was based in 4.9-rc3, so it can be queued to rc4, since it fixes a problem to all users of this model.

Thanks Daren and Greg for guiding me in the right path of stable :)

I sent a new version right now, specifying 4.8.6 and 4.4.29. Hope it's correct now!

Thanks,
