From f05b691150af4cfccbfba6cc708b9a58b9216903 Mon Sep 17 00:00:00 2001 From: Jon Mason Date: Mon, 27 Jun 2011 12:48:54 -0500 Subject: [PATCH] iwlegacy: remove unnecessary read of PCI_CAP_ID_EXP The PCIE capability offset is saved during PCI bus walking. It will remove an unnecessary search in the PCI configuration space if this value is referenced instead of reacquiring it. Signed-off-by: Jon Mason Signed-off-by: John W.
