I am pretty sure you want to call pm_runtime_enable() in bma150_probe()
so that parent controller can be suspended until somebody calls
bma150_open() and we mark the device as active (which, in turn, should
wake up its parent).

And disable should go into bma150_remove() unless I misunderstand
runtime PM framework.

I think you want to call bma150_set_mode() first and then mark device as
suspended so that parent can go to sleep as well.
Thanks.
