At this point, I would just avoid the addition of the BTMTKSDIO_INBAND_WAKEUP flag and add a new function for handling the .wakeup() callback - something like: static bool btmtksdio_sdio_inband_wakeup(struct hci_dev *hdev) { struct btmtksdio_dev *bdev = hci_get_drvdata(hdev); return device_may_wakeup(bdev->dev); } static int btmtksdio_probe(...) { .... code .... /* * If SDIO controller supports wake on Bluetooth, sending a wakeon * command is not necessary. */ if (device_can_wakeup(func->card->host->parent)) hdev->wakeup = btmtksdio_sdio_inband_wakeup; else hdev->wakeup = btmtksdio_sdio_wakeup; .... etc .... } Regards, Angelo
