[PATCH 0/6] Bluetooth: btusb: Preparation for upcoming Qualcomm QCC2072 support

[PATCH 0/6] Bluetooth: btusb: Preparation for upcoming Qualcomm QCC2072 support

[Zijun Hu]

This series collects the btusb and devcoredump changes required by the
upcoming Qualcomm QCC2072 Bluetooth driver. None of them are QCC2072-
specific: they refactor btusb into a shape that can host vendor-specific
source files, and make a few coredump helpers reusable.

Posting them as a standalone series because the QCC2072 driver itself is
larger and will take longer to review. These prerequisites are small and
self-contained, so they can hopefully be reviewed and merged on their own
in the meantime.

The series contains:
 - coredump: a readable state-name helper and a fixed-size dump header,
   both reused by the vendor driver
 - btusb: an indirect recv_intr() hook, hci_dev-based recv wrappers, a
   shared reset-prepare helper, and a split into btusb_main.c so vendor
   files can be added later

No functional change intended.

[PATCH 1/6] Bluetooth: coredump: Introduce and apply hci_devcd_state_name()

[Zijun Hu]

Introduce hci_devcd_state_name() to make devcoredump state more
readable, and apply it in coredump.c. Also remove a trailing space
in two bt_dev_dbg() format strings while applying it.

[PATCH 2/6] Bluetooth: coredump: Allow drivers to pad dump header to fixed size

[Zijun Hu]

To let a driver easily separate header and data in the generated
coredump, allow a vendor driver to pad its header to a fixed size by:
 - exposing MAX_HCI_DEVCD_HDR_SIZE as the max header size
 - exposing HCI_DEVCD_HDR_END as the header-ending marker

[PATCH 4/6] Bluetooth: btusb: Add wrappers btusb_recv_{event,acl}_hdev()

[Zijun Hu]

Vendor-specific files need to hand BT frames back to btusb for reporting
upwards after filtering out non-BT frames, but the existing helpers take
struct btusb_data *, which is private to btusb_main.c:

  int btusb_recv_event(struct btusb_data *data, struct sk_buff *skb)
  int btusb_recv_acl(struct btusb_data *data, struct sk_buff *skb)

Add two wrappers taking struct hci_dev * so they can be used from
vendor files.

I really this not a 'lets redesign btusb because our driver is not
standard Bluetooth Class' kind of thing, we already have hdev->setup
and other callbacks for vendor specific functionality, if you want
more than that perhaps it needs to be become it own driver.

>    both reused by the vendor driver
>  - btusb: an indirect recv_intr() hook, hci_dev-based recv wrappers, a
>    shared reset-prepare helper, and a split into btusb_main.c so vendor
>    files can be added later

> No functional change intended.
