x86: LLVMLinux: Fix "incomplete type const struct x86cpu_device_id"
Similar to the fix in 40413dcb7b273bda681dca38e6ff0bbb3728ef11 MODULE_DEVICE_TABLE(x86cpu, ...) expects the struct to be called struct x86cpu_device_id, and not struct x86_cpu_id which is what is used in the rest of the kernel code. Although gcc seems to ignore this error, clang fails without this define to fix the name. Code from drivers/thermal/x86_pkg_temp_thermal.c static const struct x86_cpu_id __initconst pkg_temp_thermal_ids[] = { ... }; MODULE_DEVICE_TABLE(x86cpu, pkg_temp_thermal_ids); Error from clang: drivers/thermal/x86_pkg_temp_thermal.c:577:1: error: variable has incomplete type 'const struct x86cpu_device_id' MODULE_DEVICE_TABLE(x86cpu, pkg_temp_thermal_ids); ^ include/linux/module.h:145:3: note: expanded from macro 'MODULE_DEVICE_TABLE' MODULE_GENERIC_TABLE(type##_device, name) ^ include/linux/module.h:87:32: note: expanded from macro 'MODULE_GENERIC_TABLE' extern const struct gtype##_id __mod_##gtype##_table \ ^ <scratch space>:143:1: note: expanded from here __mod_x86cpu_device_table ^ drivers/thermal/x86_pkg_temp_thermal.c:577:1: note: forward declaration of 'struct x86cpu_device_id' include/linux/module.h:145:3: note: expanded from macro 'MODULE_DEVICE_TABLE' MODULE_GENERIC_TABLE(type##_device, name) ^ include/linux/module.h:87:21: note: expanded from macro 'MODULE_GENERIC_TABLE' extern const struct gtype##_id __mod_##gtype##_table \ ^ <scratch space>:141:1: note: expanded from here x86cpu_device_id ^ 1 error generated.
