Bluetooth: btmtksdio: Fix kernel oops in btmtksdio_interrupt
Fix the following kernel oops in btmtksdio_interrrupt
[ 14.339134] btmtksdio_interrupt+0x28/0x54 [ 14.339139] process_sdio_pending_irqs+0x68/0x1a0 [ 14.339144] sdio_irq_work+0x40/0x70 [ 14.339154] process_one_work+0x184/0x39c [ 14.339160] worker_thread+0x228/0x3e8 [ 14.339168] kthread+0x148/0x3ac [ 14.339176] ret_from_fork+0x10/0x30
That happened because hdev->power_on is already called before sdio_set_drvdata which btmtksdio_interrupt handler relies on is not properly set up.
The details are shown as the below: hci_register_dev would run queue_work(hdev->req_workqueue, &hdev->power_on) as WQ_HIGHPRI workqueue_struct to complete the power-on sequeunce and thus hci_power_on may run before sdio_set_drvdata is done in btmtksdio_probe.
The hci_dev_do_open in hci_power_on would initialize the device and enable the interrupt and thus it i
