commit c4586256f0c440bc2bdb29d2cbb915f0ca785d26 upstream.
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);
