Gustavo A. R. Silva eeecf5d3a3 net: wwan: mhi_wwan_mbim: Avoid -Wflex-array-member-not-at-end warning
Use DEFINE_RAW_FLEX() to avoid a -Wflex-array-member-not-at-end warning.

Remove fixed-size array struct usb_cdc_ncm_dpe16 dpe16[2]; from struct
mbim_tx_hdr, so that flex-array member struct mbim_tx_hdr::ndp16.dpe16[]
ends last in this structure.

Compensate for this by using the DEFINE_RAW_FLEX() helper to declare the
on-stack struct instance that contains struct usb_cdc_ncm_ndp16 as a
member. Adjust the rest of the code, accordingly.

So, with these changes fix the following warning:

drivers/net/wwan/mhi_wwan_mbim.c:81:34: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end]

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 reStructuredText 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.
