If CONFIG_PM_SLEEP is not defined then the functions are defined as
NULL. And as a result we are getting build failure with
alpha allmodconfig with the error:
drivers/gpu/drm/vc4/vc4_v3d.c: In function 'vc4_v3d_set_power':
include/linux/stddef.h:7:14: error: called object is not a function or function
pointer
