38506ecefab911785d5e1aa5889f6eeb462e0954 is the first bad commit commit 38506ecefab911785d5e1aa5889f6eeb462e0954 Author: Larry Finger <larry.fin...@lwfinger.net> Date: Mon Sep 22 09:39:19 2014 -0500 rtlwifi: rtl_pci: Start modification for new drivers Future patches will move the drivers for RTL8192EE and RTL8821AE from staging to the regular wireless tree. Here, the necessary features are added to the PCI driver. Other files are touched due to changes in the various data structs.
