When compiling with clang-18 and W=1, I've noticed the following warnings: drivers/net/ethernet/cavium/liquidio/cn23xx_pf_device.c:1493:16: warning: cast from 'void (*)(struct octeon_device *, struct octeon_mbox_cmd *, void *)' to 'octeon_mbox_callback_t' (aka 'void (*)(void *, void *, void *)') converts to incompatible function type [-Wcast-function-type-strict] 1493 | mbox_cmd.fn = (octeon_mbox_callback_t)cn23xx_get_vf_stats_callback; | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ and: drivers/net/ethernet/cavium/liquidio/cn23xx_vf_device.c:432:16: warning: cast from 'void (*)(struct octeon_device *, struct octeon_mbox_cmd *, void *)' to 'octeon_mbox_callback_t' (aka 'void (*)(void *, void *, void *)') converts to incompatible function type [-Wcast-function-type-strict] 432 | mbox_cmd.fn = (octeon_mbox_callback_t)octeon_pfvf_hs_callback; | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Fix both of the above by adjusting 'octeon_mbox_callback_t' to match actual callback definitions (at the cost of adding an extra forward declaration).

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.
