Re: Elantech SMBus support regression

[Benjamin Tissoires]

Hi,

sorry for the late reply. I was always meaning to fix this the proper
way but couldn't dedicate a full day of work to go to the bottom of
elan_i2c.

Meanwhile, I am thinking at simply having a blacklist of devices that
we know are not working well (P52, L480, L580 and P72).

Could you get the value of /sys/bus/serio/devices/serio1/firmware_id
from all of these laptops?
I know the P52 is LEN2131, but I don't seem to find the other PNPIds.

Cheers,
Benjamin
