Dell XPS 13 9310: PNP: DLL0991 PNP0f13 supports

[Paul Menzel <pmenzel@xxxxxxxxxxxxx>]

Dear Linux folks,


On a Dell XPS 13 9310, Linux 5.9.1 from Debian Sid/unstable displays the 
message below.

    [    2.218614] psmouse serio1: synaptics: Your touchpad (PNP: 
DLL0991 PNP0f13) says it can support a different bus. If i2c-hid and 
hid-rmi are not used, you might want to try setting 
psmouse.synaptics_intertouch to 1 and report this to 
linux-input@xxxxxxxxxxxxxxx.

I am going to ask the user for a test of 
`psmouse.synaptics_intertouch=1`, so the ID can be added to the force 
list, but until know no Dell DLLXXXX ids show up there.


Kind regards,

Paul
