That's nice, but it breaks the build on my system:
  CC      drivers/base/platform.o
drivers/base/platform.c: In function ‘platform_pm_runtime_suspend’:
drivers/base/platform.c:970: error: implicit declaration of function ‘pm_generic_runtime_suspend’
drivers/base/platform.c: In function ‘platform_pm_runtime_resume’:
drivers/base/platform.c:975: error: implicit declaration of function ‘pm_generic_runtime_resume’
drivers/base/platform.c: In function ‘platform_pm_runtime_idle’:
drivers/base/platform.c:980: error: implicit declaration of function ‘pm_generic_runtime_idle’
make[1]: *** [drivers/base/platform.o] Error 1
make: *** [_module_drivers/base] Error 2

Care to fix it up?
