Date: Thu, 17 Jul 2014 18:58:06 +0300 From: Andrey Utkin <andrey.krieger.utkin@...il.com> To: linux-kernel@...r.kernel.org, kernel-janitors@...r.kernel.org, linux-metag@...r.kernel.org Cc: james.hogan@...tec.com, dan.carpenter@...cle.com, Andrey Utkin <andrey.krieger.utkin@...il.com> Subject: [PATCH] arch/metag/kernel/cachepart.c: 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. Changed get_thread_cache_size() to return signed int, and its result is stored into signed int variable.
