From: Luiz Augusto von Dentz <[e-mail]>

This reworks the parsing of HCI events using skb_pull_data to check
event length, in addition to that it does introduce function tables to
handle events, LE subevents, Command Complete and Command Status which
simplify the callback by adding a common code that uses skb_pull_data
when parsing such events.

Luiz Augusto von Dentz (15):
  skbuff: introduce skb_pull_data
  Bluetooth: HCI: Use skb_pull_data to parse BR/EDR events
  Bluetooth: HCI: Use skb_pull_data to parse Command Complete event
  Bluetooth: HCI: Use skb_pull_data to parse Number of Complete Packets
    event
  Bluetooth: HCI: Use skb_pull_data to parse Inquiry Result event
  Bluetooth: HCI: Use skb_pull_data to parse Inquiry Result with RSSI
    event
  Bluetooth: HCI: Use skb_pull_data to parse Extended Inquiry Result
    event
  Bluetooth: HCI: Use skb_pull_data to parse LE Metaevents
  Bluetooth: HCI: Use skb_pull_data to parse LE Advertising Report event
  Bluetooth: HCI: Use skb_pull_data to parse LE Ext Advertising Report
    event
  Bluetooth: HCI: Use skb_pull_data to parse LE Direct Advertising
    Report event
  Bluetooth: hci_event: Use of a function table to handle HCI events
  Bluetooth: hci_event: Use of a function table to handle LE subevents
  Bluetooth: hci_event: Use of a function table to handle Command
    Complete
  Bluetooth: hci_event: Use of a function table to handle Command Status
