Kees Cook 204bb85286 wifi: brcmfmac: cyw: Fix __counted_by to be LE variant
In brcmf_cyw_mgmt_tx() the "len" counter of the struct
brcmf_mf_params_le::data flexible array is stored as little-endian via
cpu_to_le16() so the __counted_by_le() variant must be used:

	struct brcmf_mf_params_le *mf_params;
	...
	mf_params_len = offsetof(struct brcmf_mf_params_le, data) +
			(len - DOT11_MGMT_HDR_LEN);
	mf_params = kzalloc(mf_params_len, GFP_KERNEL);
	...
        mf_params->len = cpu_to_le16(len - DOT11_MGMT_HDR_LEN);

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.
