From da065a5c524c0ea2589d12f69884b2f8305dc6d4 Mon Sep 17 00:00:00 2001 From: Arend van Spriel Date: Tue, 3 May 2011 11:35:35 +0200 Subject: [PATCH] staging: brcm80211: remove unused functions from hndpmu.c The source file contained several functions that are not being used in the brcmsmac and/or brcmfmac driver. These functions have been removed.
