From db3f5d0df9af1e5965e64595595a6a719c42fcf3 Mon Sep 17 00:00:00 2001 From: Alexander Aring Date: Sun, 17 May 2015 21:45:00 +0200 Subject: fakelb: rename fakelb_dev_priv to fakelb_phy This patch renames fakelb_dev_priv to fakelb_phy. We don't faking devices here, we fake wpan phys. This avoids also confusing with the variable priv, which is used several times in this driver to represent this structure.
