From c523ea78ec9a33586fa7a73859de7c462097cdfc Mon Sep 17 00:00:00 2001 From: Brett Rudley Date: Wed, 1 Dec 2010 15:36:39 -0800 Subject: [PATCH] staging: brcm80211: absorb linux_osl.h into osl.h Move code from linux_osl.h into osl.h and delete linux_osl.h, which created a bunch of checkpatch errors... I fixed most but volatile warnings will have to be dealt with later.
