From 68dd49ef907f92127aabb30b3368b80eb0ffb459 Mon Sep 17 00:00:00 2001 From: Jon Mason <jdmason@kudzu.us> Date: Thu, 30 Jun 2011 10:42:47 -0500 Subject: [PATCH] iwlwifi: 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.
