Billy Tsai 6866c91f8c i3c: Remove the const qualifier from i2c_msg pointer in i2c_xfers API
The change is necessary to enable the use of the
`i2c_get_dma_safe_msg_buf()` API, which requires a non-const
`struct i2c_msg *` to operate. The `i2c_get_dma_safe_msg_buf()` function
ensures safe handling of I2C messages when using DMA, making it essential
for scenarios where DMA transfers are involved. By removing the `const`
qualifier, this patch allows drivers to prepare and manage DMA-safe
buffers directly.

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.
