Right click does not work on Dell M3800 Synaptics clickpad

[Po-Hsu Lin]

Right click on the clickpad does not work.

Looks like the right button has been recognized as a left button.

[ 2.536487] psmouse serio1: synaptics: Your touchpad (PNP: DLL060d 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 <email address hidden>.

It may want to use SMBus (i.e. i2c_i801). Try removing it from blacklist, or upgrade kmod in disco-proposed.
