Subject: [PATCH v6 06/13] PCI: designware: Fix one potential assignment error of cfg start
Date: Thu, 16 Oct 2014 15:52:36 +0800 [thread overview]
Message-ID: <1413445963-24706-7-git-send-email-richard.zhu@freescale.com> (raw)
In-Reply-To: <1413445963-24706-1-git-send-email-richard.zhu@freescale.com>
From: Richard Zhu <r65037@freescale.com>
if va_cfg0_base/va_cfg1_base are initialized by
designware core, the pp->cfg.start is not initialized
properly, when IORESOURCE_MEM "config" is represented
as cfg space resource.
solution: assign cfg_res->start to pp->cfg.start.
