using wakelock in 4.9 kernel driver

I'm trying to port a touchscreen driver that was written in 2014 for a device running Android Q (Hikey 960 on AOSP). The module won't compile because of: 

#include <linux/wakelock.h>

which isn't there in the Linaro 4.9 kernel that the Hikey 960 board uses with AOSP.

Apparently, the functionality is there in kernel/power/wakelock.c and kernel/power/power.h, but I don't know how to compile that into my module. Or if I'm still even supposed to make use of wakelocks in driver modules like this? There must be a good reason the wakelock.h is not there any longer?
