This appears to break keyboard on HP's 15-da1xxx which appears to have 
the same ID: SYN3286. This happens on 6.0.12.

synaptics excerpt from dmesg:
psmouse serio1: synaptics: Trying to set up SMBus access

This was reported downstream as a regression between 6.0.10 and 6.0.12:
https://bugzilla.suse.com/show_bug.cgi?id=1206358

Full dmesgs available there too.


6.0.10 has this instead of the above:
psmouse serio1: synaptics: queried max coordinates: x [..5648], y [..4826]
psmouse serio1: synaptics: queried min coordinates: x [1292..], y [1026..]
psmouse serio1: synaptics: Your touchpad (PNP: SYN3286 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@vger.kernel.org.
