From 2e08396da0d185d81101e96de3ac4bc65b96d2fa Mon Sep 17 00:00:00 2001 From: Arend van Spriel Date: Tue, 13 Sep 2011 09:49:50 +0200 Subject: [PATCH] staging: brcm80211: remove devpath related nvram variable lookup The lookup function used for the devpath related functions did not provide a variable table so the lookup would always fail. As this makes the functions pretty useless these have been removed.
