[ Upstream commit 87be7b189b2c50d4b51512f59e4e97db4eedee8a ]
__hci_cmd_sync_status shall only be used if hci_req_sync_lock is _not_
required which is not the case of hci_dev_cmd so it needs to use
hci_cmd_sync_status which uses hci_req_sync_lock internally.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
