Hi, this is your Linux kernel regression tracker.

This reverts commit 37ef4c19b4c659926ce65a7ac709ceaefb211c40.
The touchpad present in the Dell Precision 7550 and 7750 laptops reports a HID_DG_BUTTONTYPE of type MT_BUTTONTYPE_CLICKPAD. However, the device is not a clickpad, it is a touchpad with physical buttons.
In order to fix this issue, a quirk for the device was introduced in libinput [1] [2] to disable the INPUT_PROP_BUTTONPAD property:
[Precision 7x50 Touchpad] MatchBus=i2c MatchUdevType=touchpad MatchDMIModalias=dmi:*svnDellInc.:pnPrecision7?50* AttrInputPropDisable=INPUT_PROP_BUTTONPADHowever, because of the change introduced in 37ef4c19b4 ("Input: clear BTN_RIGHT/MIDDLE on buttonpads") the BTN_RIGHT key bit is not mapped anymore breaking the device right click button and making impossible to workaround it in user space.
In order to avoid breakage on other present or future devices, revert the patch causing the issue.

Jiri, Benjamin, what the status here? Sure, this is not a crucial regression and we are in the middle of the merge window, but it looks like nothing has happened for a week now. Or was progress made somewhere and I just missed it?
No, I think it just wasn't picked up by the input maintainer yet (Dmitry, now in CC).
FWIW: Acked-by: Benjamin Tissoires benjamin.tissoires@redhat.com
José, please do not forget to add the input maintainer when you target the input tree, not the HID one :)
Cheers, Benjamin

Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat)
P.S.: As the Linux kernel's regression tracker I'm getting a lot of reports on my table. I can only look briefly into most of them and lack knowledge about most of the areas they concern. I thus unfortunately will sometimes get things wrong or miss something important. I hope that's not the case here; if you think it is, don't hesitate to tell me in a public reply, it's in everyone's interest to set the public record straight.
