Paul Walmsley b7776a802f riscv: hwprobe: avoid uninitialized variable use in hwprobe_arch_id() ... Resolve this smatch warning: arch/riscv/kernel/sys_hwprobe.c:50 hwprobe_arch_id() error: uninitialized symbol 'cpu_id'. This could happen if hwprobe_arch_id() was called with a key ID of something other than MVENDORID, MIMPID, and MARCHID. This does not happen in the current codebase. The only caller of hwprobe_arch_id() is a function that only passes one of those three key IDs. For the sake of reducing static analyzer warning noise, and in the unlikely event that hwprobe_arch_id() is someday called with some other key ID, validate hwprobe_arch_id()'s input to ensure that 'cpu_id' is always initialized before use.
