Bluetooth: btsdio: Do not bind to non-removable BCM43341 commit b4cdaba274247c9c841c6a682c08fa91fb3aa549 upstream. BCM43341 devices soldered onto the PCB (non-removable) always (AFAICT) use an UART connection for bluetooth. But they also advertise btsdio support on their 3th sdio function, this causes 2 problems: 1) A non functioning BT HCI getting registered 2) Since the btsdio driver does not have suspend/resume callbacks, mmc_sdio_pre_suspend will return -ENOSYS, causing mmc_pm_notify() to react as if the SDIO-card is removed and since the slot is marked as non-removable it will never get detected as inserted again. Which results in wifi no longer working after a suspend/resume. This commit fixes both by making btsdio ignore BCM43341 devices when connected to a slot which is marked non-removable.

Bluetooth: Move handling of HCI_RUNNING flag into core Setting and clearing of HCI_RUNNING flag in each and every driver is just duplicating the same code all over the place. So instead of having the driver do it in their hdev->open and hdev->close callbacks, set it globally in the core transport handling.

Bluetooth: Add hdev parameter to hdev->send driver callback Instead of masking hdev inside the skb->dev parameter, hand it directly to the driver as a parameter to hdev->send. This makes the driver interface more clear and simpler. This patch fixes all drivers to accept and handle the new parameter of hdev->send callback. Special care has been taken for bpa10x and btusb drivers that require having skb->dev set to hdev for the URB transmit complete handlers.

Bluetooth: Rename HCI_BREDR into HCI_PRIMARY The HCI_BREDR naming is confusing since it actually stands for Primary Bluetooth Controller. Which is a term that has been used in the latest standard. However from a legacy point of view there only really have been Basic Rate (BR) and Enhanced Data Rate (EDR). Recent versions of Bluetooth introduced Low Energy (LE) and made this terminology a little bit confused since Dual Mode Controllers include BR/EDR and LE. To simplify this the name HCI_PRIMARY stands for the Primary Controller which can be a single mode or dual mode controller.
