[ Upstream commit 8a20030038742b9915c6d811a4e6c14b126cafb4 ]
Sparse reports
net/ipv4/inet_diag.c:1511:17: sparse: sparse: Using plain integer as NULL pointer
Due to this code calling cmpxchg on a non-integer type
struct inet_diag_handler *
return !cmpxchg((const struct inet_diag_handler**)&inet_diag_table[type],
NULL, h) ? 0 : -EEXIST;
While hexagon's cmpxchg assigns an integer value to a variable of this
type.
__typeof__(*(ptr)) __oldval = 0;
Update this assignment to cast 0 to the correct type.
The original issue is easily reproduced at head with the below block,
and is absent after this change.
make LLVM=1 ARCH=hexagon defconfig
make C=1 LLVM=1 ARCH=hexagon net/ipv4/inet_diag.o

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.
