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; Reported-by: Nathan Chancellor <nathan@kernel.org> Closes: https://github.com/ClangBuiltLinux/linux/issues/1910 Signed-off-by: Justin Stitt <justinstitt@google.com> Reviewed-by: Nathan Chancellor <nathan@kernel.org> Link: https://lore.kernel.org/r/20230816-void-drivers-leds-leds-pca955x-v1-1-2967e4c1bdcc@google.com Signed-off-by: Lee Jones <lee@kernel.org>
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.
