The new 6.7-rc1 kernel now checks the checksum on CDAT data. While
using a branch of Fan's DCD qemu work (and specifying DCD devices), the
following splat was observed.
WARNING: CPU: 1 PID: 1384 at drivers/base/devres.c:1064 devm_kfree+0x4f/0x60
...
RIP: 0010:devm_kfree+0x4f/0x60
...
? devm_kfree+0x4f/0x60
read_cdat_data+0x1a0/0x2a0 [cxl_core]
cxl_port_probe+0xdf/0x200 [cxl_port]
...
The issue in qemu is still unknown but the spat is a straight forward
bug in the CDAT checksum processing code. Use a CDAT buffer variable to
ensure the devm_free() works correctly on error.

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.
