[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.
