Hans de Goede 03eb283523 mei: vsc: Cast tx_buf to (__be32 *) when passed to cpu_to_be32_array() 
[ Upstream commit 97ce0fe2b7 ]

Commit f88c0c72ff ("mei: vsc: Use struct vsc_tp_packet as vsc-tp tx_buf
and rx_buf type") changed the type of tx_buf from "void *" to "struct
vsc_tp_packet *" and added a cast to (u32 *) when passing it to
cpu_to_be32_array() and the same change was made for rx_buf.

This triggers the type-check warning in sparse:

vsc-tp.c:327:28: sparse: expected restricted __be32 [usertype] *dst
vsc-tp.c:327:28: sparse: got unsigned int [usertype] *

vsc-tp.c:343:42: sparse: expected restricted __be32 const [usertype] *src
vsc-tp.c:343:42: sparse: got unsigned int [usertype] *

Fix this by casting to (__be32 *) instead.

Note actually changing the type of the buffers to "be32 *" is not an option
this buffer does actually contain a "struct vsc_tp_packet" and is used
as such most of the time. vsc_tp_rom_xfer() re-uses the buffers as just
dumb arrays of 32 bit words to talk to the device before the firmware has
booted, to avoid needing to allocate a separate buffer.

Fixes: f88c0c72ff ("mei: vsc: Use struct vsc_tp_packet as vsc-tp tx_buf and rx_buf type")

README 

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.
