arch/x86/kernel/cpu/intel_cacheinfo.c: In function ‘init_intel_cacheinfo’: arch/x86/kernel/cpu/intel_cacheinfo.c:642:28: warning: ‘this_leaf.size’ may be used uninitialized in this function [-Wmaybe-uninitialized] arch/x86/kernel/cpu/intel_cacheinfo.c:643:29: warning: ‘this_leaf.eax.split.num_threads_sharing’ may be used uninitialized in this function [-Wmaybe-uninitialized] This keeps on happening during randbuilds and the compiler is wrong here: In the case where cpuid4_cache_lookup_regs() returns 0, both this_leaf.size and this_leaf.eax get initialized. In the case where the CPUID leaf doesn't contain valid cache info, we error out which init_intel_cacheinfo() handles correctly without touching the abovementioned fields. So shut up the warning by clearing out the struct which we hand down. While at it, reverse error handling and gain one indentation level.
