That's nice, but it breaks the build on my system:
  CC      drivers/base/platform.o
drivers/base/platform.c: In function âplatform_pm_runtime_suspendâ:
drivers/base/platform.c:970: error: implicit declaration of function âpm_generic_runtime_suspendâ
drivers/base/platform.c: In function âplatform_pm_runtime_resumeâ:
drivers/base/platform.c:975: error: implicit declaration of function âpm_generic_runtime_resumeâ
drivers/base/platform.c: In function âplatform_pm_runtime_idleâ:
drivers/base/platform.c:980: error: implicit declaration of function âpm_generic_runtime_idleâ
make[1]: *** [drivers/base/platform.o] Error 1
make: *** [_module_drivers/base] Error 2

Care to fix it up?

thanks,
