[ Upstream commit 132d0fd0b8418094c9e269e5bc33bf5b864f4a65 ] For some controllers such as QCA2066, it does not need to send HCI_Configure_Data_Path to configure non-HCI data transport path to support HFP offload, their device drivers may set hdev->get_codec_config_data as NULL, so Explicitly add this non NULL checking before calling the function.

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.
