[PATCH v2] platform/x86/asus-nb-wmi.c: Add X45U quirk

[PATCH v2] 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.

This patch applies smoothly in 4.8.6 and 4.4.29. I hope now I followed
the instructions correctly.

v1 -> v2:
 Add stable copy and specify the stable version to apply this patch

Hi Marcos,

You'll find exact steps in the stable_kernel_rules.txt document regarding how to
annotate the commit message with Cc lines indicating to which versions this
patch should be applied.

If, for example, you have verified that this patch is relevant only to 4.4 and
forward, you would include:

Cc: <stable@vger.kernel.org> # 4.4.x-

But this should mean that the patch is explicitly broken or otherwise
inappropriate for 4.3 and earlier.

Thanks,

Yes, I have misread the documentation. I could apply the patch as is just in
the versions 4.8.6 and 4.4.29, but maybe I could rework te patch earlier versions.

But, aside from stable tree, do you agree with this change, since it fixes the
wireless problem in this laptop?

Yes, no objection to the patch. It happened to land right about the time we were
having the "be better about how you manage your stable commits" discussion at
kernel summit, so it got some extra focus :-)

Care to resend with the Cc stable tag corrected?

Absolutely not. I just sent a new version with the version along with
the stable email.

Thanks for your patience in this subject :)

I had some problem to send the patch through git send-email and mutt,
because the stable address and the version always got merged. So Laura
Abbott helped me with the tip of --suppress-cc=bodycc, and then I added
stable address manually.

Is there a new procedure to send a patch to stable, without being this
tricky? Is there is, I would be happy to send a patch to fix our
documentation, since even people from kernel newbies are suffering by
the same problem[1]

Thanks in advance.
