Bluetooth: hci_qca: Pass boolean 'on/off' to qca_send_power_pulse()
There are only two types of power pulses 'on' or 'off', pass a boolean instead of the power pulse 'command'. Signed-off-by: Matthias Kaehlcke <mka@chromium.org> Reviewed-by: Balakrishna Godavarthi <bgodavar@codeaurora.org> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
