[PATCH v1 1/1] Bluetooth: hci_qca: only assign wakeup with serial port support

From: Zhengping Jiang
Date: Thu Oct 13 2022 - 17:45:25 EST


Only assign hdev->wakeup if the serial port supports wakeup. Otherwise
it will fall back to the hci_uart_wakeup or the behavior that can be
overridden before calling the hci_uart_register_device().
