This patch aims to resolve the issue raised here:
https://bugzilla.kernel.org/show_bug.cgi?id=120181
The issue is in relation to an Asus touchpad device which currently does not have
multitouch support.
The device currently falls through to the hid-generic driver which
treats the device as a mouse.
This patch aims to add the multitouch support.
A DKMS driver has been developed to test this and can found here:
https://github.com/vlasenko/hid-asus-dkms
GitHub statistics show that this repository has had over 100 unique cloners.
We have also been able to resolve over 20 raised issues with each user confirming
the driver is working well for them. There are currently no outstanding issues
directly related to this driver.

The comments above should be in the commit message.
Besides that and only one nitpick below, I don't have much to add.
I have helped a little bit the development on github which explains why
I can't find much to say ( I already complained :-P ).
There is at least an other device that would require to be added later,
which is the bluetooth cover of some Asus tablet IIRC. The protocol is
slightly different and we will need to keep both the keyboard and the
touchpad around, but it could be added later in an other patch.
For me, the patch is:

Good point, that's not for any good.
I've dropped this change, ammended the changelog (also indicating the
changes I've done on top of the patch), and applied to for-4.10/asus.

The previous submission which added Touchpad support broke the
Keyboard support of this driver. This patch:
1. fixes the Keyboard support (by assigning drvdata->input);
2. renames NOTEBOOK_QUIRKS to KEYBOARD_QUIRKS;
3. adds the NO_INIT_REPORT quirk to the KEYBOARD_QUIRKS; and
4. sets the input->name to 'Asus Keyboard' for the keyboard

Hi Brendan,
Sorry for breaking the existing device.
I have a few minor issues with your patch, but I'll let Jiri says
whether or not you need a v2.

This is actually what was breaking your keyboard (plus item 4 which is
cosmetic). Ideally, this should be in a separate patch.
> 2. renames NOTEBOOK_QUIRKS to KEYBOARD_QUIRKS;

Points 2 and 3 are actually improvements because I can't seem to find
that previously the keyboard had this quirk. I understand it is
valuable, but it should be in a different patch IMO.
> 4. sets the input->name to 'Asus Keyboard' for the keyboard
Cosmetic, but so important :)
Anyway, the patch in its current form is:
Reviewed-by: Benjamin Tissoires <benjamin.tissoires@redhat.com>
But it might be good to split it in 2 (it will depend on Jiri I guess).
Let's hope we won't break the touchpad this time :)
Cheers,
Benjamin

Having it separate would be slightly better next time, but I don't
consider that really to be a show stopper. Queuing in
for-4.10/upstream-fixes, thanks.
