When building with clang 18 I see the following warning: | drivers/dma/owl-dma.c:1119:14: warning: cast to smaller integer type | 'enum owl_dma_id' from 'const void *' [-Wvoid-pointer-to-enum-cast] | 1119 | od->devid = (enum owl_dma_id)of_device_get_match_data(&pdev->dev); This is due to the fact that `of_device_get_match_data()` returns a void* while `enum owl_dma_id` has the size of an int. Cast result of `of_device_get_match_data()` to a uintptr_t to silence the above warning for clang builds using W=1 Link: https://github.com/ClangBuiltLinux/linux/issues/1910 Reported-by: Nathan Chancellor <nathan@kernel.org> Signed-off-by: Justin Stitt <justinstitt@google.com> Acked-by: Manivannan Sadhasivam <mani@kernel.org> Link: https://lore.kernel.org/r/20230816-void-drivers-dma-owl-dma-v1-1-a0a5e085e937@google.com Signed-off-by: Vinod Koul <vkoul@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.
