I have virtually the same messages on a Asus T100CHI (Z3775) a baytrail

[    2.661024] pwm-lpss 80860F09:00: invalid resource
[    2.661126] pwm-lpss: probe of 80860F09:00 failed with error -22

backlight control works anyway

pwm-lpss 80860F09 invalid resource error message with 4.14.


Had to downgrade kernel from 4.14 to 4.9 in order to boot. Intel Bay Trail-M Dual Core Celeron N2840 Processor.

"pwm-lpss 80860F09:00: invalid resource" is still in dmesg in 4.15.18
Good news is the message is gone from 4.16.3 and 4.17-rc1

Checked on Asus T100CHI running Ubuntu 18.04
