[PATCH 00/11] Bluetooth: Miscellaneous fixes and cleanups

This series collects simple, independent fixes and cleanups for the
Bluetooth core and USB/SDIO transport drivers.

Every patch is simple and self-contained: two bug fixes for btintel,
the rest are readability cleanups and two trivial ACL helpers
(hci_acl_handle()/hci_acl_dlen()) with their users.
