Subject: [PATCH] Input: synaptics - remove TOPBUTTONPAD property for Lenovos
|
|
2015
|
|
|
|
The 2015 series of the Lenovo thinkpads added back the hardware buttons on
|
|
top of the touchpad for the trackstick.
|
|
|
|
Unfortunately, Lenovo used the PNPIDs that are supposed to be "5 buttons"
|
|
touchpads, so the new laptops also have the INPUT_PROP_TOPBUTTONPAD. Yay!
|
|
|
|
Instead of manually removing each of the new ones, or hoping that we know
|
|
all the current ones, we can consider that the PNPIDs list that were given
|
|
contains touchpads that have the trackstick buttons, either physically
|
|
wired to them, or emulated with the top software button property.
|
|
|
|
Thanks to the extra buttons capability in query $10, we can reliably detect
|
|
the physical buttons from the software ones, and so we can remove the
|
|
TOPBUTTONPAD property even if it was declared as such.
