In preparation to enabling -Wimplicit-fallthrough, this patch silences the following warning: drivers/gpu/drm/amd/amdgpu/../amdkfd/kfd_mqd_manager_v10.c: In function ‘mqd_manager_init_v10’: ./include/linux/dynamic_debug.h:122:52: warning: this statement may fall through [-Wimplicit-fallthrough=] #define __dynamic_func_call(id, fmt, func, ...) do { \ ^ ./include/linux/dynamic_debug.h:143:2: note: in expansion of macro ‘__dynamic_func_call’ __dynamic_func_call(__UNIQUE_ID(ddebug), fmt, func, ##__VA_ARGS__) ^~~~~~~~~~~~~~~~~~~ ./include/linux/dynamic_debug.h:153:2: note: in expansion of macro ‘_dynamic_func_call’ _dynamic_func_call(fmt, __dynamic_pr_debug, \ ^~~~~~~~~~~~~~~~~~ ./include/linux/printk.h:336:2: note: in expansion of macro ‘dynamic_pr_debug’ dynamic_pr_debug(fmt, ##__VA_ARGS__) ^~~~~~~~~~~~~~~~ drivers/gpu/drm/amd/amdgpu/../amdkfd/kfd_mqd_manager_v10.c:432:3: note: in expansion of macro ‘pr_debug’ pr_debug("%s@%i\n", __func__, __LINE__); ^~~~~~~~ drivers/gpu/drm/amd/amdgpu/../amdkfd/kfd_mqd_manager_v10.c:433:2: note: here case KFD_MQD_TYPE_COMPUTE: ^~~~ by removing the call to pr_debug() in KFD_MQD_TYPE_CP: "The mqd init for CP and COMPUTE will have the same routine."

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.
