install_equiv_cpu_table() returns type int.  It uses negative error
codes so using an unsigned type breaks the error handling.

How did you notice this btw - did GCC throw a warning?

It's a smatch warning.

arch/x86/kernel/microcode_amd.c +256 generic_load_microcode(12)
	warn: unsigned 'offset' is never less than zero.
