From 20e5ca16397648811a9e1ad531360c843e005a57 Mon Sep 17 00:00:00 2001 From: Arend van Spriel Date: Tue, 18 Oct 2011 14:03:09 +0200 Subject: brcm80211: util: move brcmu_pktfrombuf() function to brcmfmac The function brcmu_pktfrombuf was only used in the brcmfmac source and has been moved there. It has been refactored to match its use.
