From 56d52fcc6682f170495db6a1b26c3f50083e1160 Mon Sep 17 00:00:00 2001 From: Arend van Spriel Date: Wed, 29 Jun 2011 16:47:48 -0700 Subject: [PATCH] staging: brcm80211: rename function variables The fullmac driver uses dhd as variable name for the driver instance in a number of functions. This has been changed to a more generic name as the dhd is not meaningful (broadcom internal name).
