Justin Stitt a09af0551f leds: pca955x: Fix -Wvoid-pointer-to-enum-cast warning
When building with clang 18 I see the following warning:
|      drivers/leds/leds-pca955x.c:487:15: warning: cast to smaller integer
|      type 'enum pca955x_type' from 'const void *' [-Wvoid-pointer-to-enum-cast]
|        487 |                 chip_type = (enum pca955x_type)md;

This is due to the fact that `md` is a void* while `enum pca995x_type` has the
size of an int.

Add uintptr_t cast to silence clang warning while also keeping enum cast
for readability and consistency with other `chip_type` assignment just a
few lines below:
|	chip_type = (enum pca955x_type)id->driver_data;

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.
