metag: cachepart: Fix failure check
[linux-3.16-rc5/arch/metag/kernel/cachepart.c:102]: (style) Checking if unsigned variable 'thread_cache_size' is less than zero. Source code is if (thread_cache_size < 0) pr_emerg("Can't read %s cache size\n", cache_type ? "DCACHE" : "ICACHE"); but unsigned int thread_cache_size; Function get_thread_cache_size returns an error code as (unsigned int) -1. Change get_thread_cache_size() to return signed int, and its result is stored into signed int variable.
