module: Remove const attribute from alias for MODULE_DEVICE_TABLE
MODULE_DEVICE_TABLE(type, name) creates an alias of type 'extern const
typeof(name)'. If 'name' is already constant the 'const' attribute is
specified twice, which is not allowed in C89 (see discussion at
https://lkml.org/lkml/2017/5/23/1440). Since the kernel is built with
-std=gnu89 clang generates warnings like this:
drivers/thermal/x86_pkg_temp_thermal.c:509:1: warning: duplicate 'const'
declaration specifier
[-Wduplicate-decl-specifier]
MODULE_DEVICE_TABLE(x86cpu, pkg_temp_thermal_ids);
^
./include/linux/module.h:212:8: note: expanded from macro 'MODULE_DEVICE_TABLE'
extern const typeof(name) __mod_##type##__##name##_device_table
Remove the const attribute from the alias to avoid the duplicate
specifier. After all it is only an alias and the attribute shouldn't
have any effect.
