Marcel Holtmann 01009eec70 Bluetooth: hci_uart: Remove the manual protocol init message
The init function for each HCI UART protocol prints the same on success
and failure. This information is so generic, remove it and let the main
HCI UART handling print it instead.

Marcel Holtmann 7c40fb8db1 Bluetooth: hci_uart: Add name information to hci_uart_proto struct
This adds an extra name field to the hci_uart_proto struct that provides
a simple way of adding a string identifier to the protocol.

Marcel Holtmann 4ee7ef1989 Bluetooth: hci_uart: Make struct hci_uart_proto always const
The usage of struct hci_uart_proto should always be const. Change the
function headers and individual protocol drivers.

Marcel Holtmann 9d1c40ebb6 Bluetooth: hci_uart: Use const data pointer for received data
The TTY layer provides its data pointers as const, but the HCI UART
callbacks expect them as general data pointers. This is of course
wrong and instead of casting them, just fix the individual drivers
to actually take a const data pointer.

Marcel Holtmann 7bd8f09f69 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.

Marcel Holtmann e1a2617069 Bluetooth: Provide hdev parameter to hci_recv_frame() driver callback
To avoid casting skb->dev into hdev, just let the drivers provide
the hdev directly when calling hci_recv_frame() function.

This patch also fixes up all drivers to provide the hdev.

David Herrmann 9eb648c39a Bluetooth: hci-uart-ll: Use GFP_ATOMIC in open()
The uart_proto open() callback is not called in atomic context so we can safely
sleep here. The caller hci_uart_set_proto() in hci_ldisc.c is an ioctl() handler
and therefore can sleep.
