I am not sure what you mean? Are you suggesting something like:
bma150_set_mode(bma150->client, BMA150_MODE_NORMAL);
return pm_runtime_get_sync(&bma150->client->dev);

That would cause multiple bma150_set_mode() calls since
pm_runtime_get_sync() will trigger one if needed.

As for the rest of your comments I agree and will make sure to update
them for next version.
