The dell-wmi-sysman and think-lmi kernel modules both have a global
struct class *fw_attr_class variable, leading to the following compile
errors when both are builtin:
ld: drivers/platform/x86/think-lmi.o:(.bss+0x0): multiple definition of `fw_attr_class'; drivers/platform/x86/dell/dell-wmi-sysman/sysman.o:(.bss+0x0): first defined here
In both cases the variable is only used in the file where it is declared.
Make both declarations static to avoid the linker error.
