Bluetooth: hci_bcm: Streamline runtime PM code
This driver seeks to force the Bluetooth device on for the duration of
5 seconds when the Bluetooth device has woken the host and after a
complete packet has been received. It does that by calling:
pm_runtime_get();
pm_runtime_mark_last_busy();
pm_runtime_put_autosuspend();
The same can be achieved more succinctly with:
pm_request_resume();
That's because after runtime resuming the device, rpm_resume() invokes
pm_runtime_mark_last_busy() followed by rpm_idle(), which will cause
the device to be suspended after expiration of the autosuspend_delay.
No functional change intended.
