[PATCH v2 0/4] Bluetooth: btusb: Support Qualcomm multi-subsystem QCC2072

[Zijun Hu <zijun.hu@oss.qualcomm.com>]

Hi Luiz,

This revision addresses issues below you raised in our previous discussion.
Could you take a look at this new revision when you get a chance, and let
me know if you have any further comments?

- Pre-process the PERI frame
- Don't hci_send_to_monitor() for PERI frame
- Don't use the safer skb_pull_data() helper

A malformed PERI frame, once identified for what it is, is sometimes still
valuable, so don't drop it early via a min_len/max_len check.
For example, a malformed memdump frame needs to reach its final handler to
abort an in-progress memdump procedure.

This patch series is to support Qualcomm multi-subsystem QCC2072, the
first 3 commits are simple dependencies of the last one, previously
sent separately but now combined into this series, each commit includes
its own changelog below the commit message.
