[PATCH v1 0/1] Bluetooth: hci_qca: only assign wakeup with serial port support

[Zhengping Jiang]

This patch will check if the serial port supports wakeup before assigning
the hdev->wakeup callback. After landing the 'commit c1a74160eaf1a
("Bluetooth: hci_qca: Add device_may_wakeup support")', the wake-on-bt
was broken in Jacuzzi because the qca_wakeup returns false. In this case
it will fall back to the default hci_uart_wakeup.

Changes in v1:
- Check serial port support before assigning wakeup callback

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

[Zhengping Jiang]

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().
