From b9d146e30a2d855229f0944152f84aef1a21553b Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Wed, 5 Dec 2012 13:51:20 -0700 Subject: iwlwifi: collapse wrapper for pcie_capability_read_word() iwl_pciexp_link_ctrl() has only one call site and no longer provides any useful abstraction, so collapse it into the caller.
