This file doesn't include the word "LED".
$ grep -i led drivers/platform/x86/intel_cht_int33fe.c $
Examining it... this is an ACPI driver, Intel's Not-Invented-Here proprietary device tree.
So I should convert an sh7760 board to ACPI? How would this fix the problem where the driver's probe function expects a structure as input that is locally defined, instead of the generic structure from linux/leds.h it used to accept?
If we feed the probe function NULL platform data _and_ don't have device tree enabled, doesn't it error out?
