Hello,
I have just installed the new Linux 4.12 kernel.
My ELAN touchpad is still completely dead.
Please find attached the complete dmesg output file here (comment #75):

FWIW,
1. verify the return value of irq_get_trigger_type()
[ 4.478815] i2c_hid i2c-ELAN1203:00: Trigger type: 0
2. Force the trigger type to IRQ_TYPE_EDGE_FALLING with
irqd_set_trigger_type() before request_threaded_irq() 3. reboot with
your own kernel to see if it works.
I also set the type to IRQ_TYPE_EDGE_FALLING. But looks like it didn't
work for the user.
