When building with clang 18 I see the following warning: | drivers/soc/renesas/rmobile-sysc.c:193:22: warning: cast to smaller integer | type 'enum pd_types' from 'const void *' [-Wvoid-pointer-to-enum-cast] | 193 | add_special_pd(np, (enum pd_types)id->data); This is due to the fact that `id->data` is a void* and `enum pd_types` has the size of an integer. This cast from pointer-width to int-width causes truncation and possible data loss. Instead, cast to `uintptr_t` which has the same width as void*.

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.
