Comment 21 for bug 1700657

The previous entries in dmesg was with @coolstar's patch and with the patch to elan_i2c_core.c,
only applying @coolstar's patch for v4.13rc1 i see this in dmesg:

[ 8.995266] i2c_hid i2c-ELAN0651:00: i2c-ELAN0651:00 supply vdd not found, using dummy regulator
[ 10.620352] i2c_hid i2c-ELAN0651:00: can't add hid device: -5
[ 10.620578] i2c_hid: probe of i2c-ELAN0651:00 failed with error -5

The kernel module seems to load:

$ dmesg | grep -i intel_lpss_pci

but it doesn't look like it is getting used:
