Date: Thu, 4 Jun 2015 10:18:46 +0800 From: Wei Yang <weiyang@...ux.vnet.ibm.com> To: yinghai@...nel.org Cc: x86@...nel.org, linux-kernel@...r.kernel.org, Wei Yang <weiyang@...ux.vnet.ibm.com> Subject: [PATCH] x86, setup: code clean of e820_reserve_setup_data() pa_data and found are highly related, so there is no need to set a found flag. This patch removes the found and just return when pa_data is NULL.
