Message-Id: <1222578476-25691-1-git-send-email-qingtao.cao@windriver.com> Date: Sun, 28 Sep 2008 13:07:56 +0800 From: qingtao.cao@...driver.com To: linux-kernel@...r.kernel.org Cc: yanmin.zhang@...el.com Subject: [PATCH] PCIE: use PCI_EXT_CAP_NEXT to traverse PCIE extended capability list. PCIE extended capability unit is of 4-byte, so the least 2 bits of the most significant 12 bits should be masked off to zero when accessing the extended capability list.
