Given the safety requirements of as_slice_mut() and write() taking an
immutable reference is technically not incorrect.
However, let's leverage the compiler's capabilities and require a
mutable reference to ensure exclusive access.
This also fixes a clippy warning introduced with 1.88:
warning: mutable borrow from immutable input(s)
--> rust/kernel/dma.rs:297:78

297 | pub unsafe fn as_slice_mut(&self, offset: usize, count: usize) -> Result<&mut [T]> {
| ^^^^^^^^

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.
