[PATCH 9/9] staging: brcm80211: move utility functions into new module

Arend van Spriel arend at broadcom.com
Mon May 9 14:33:10 UTC 2011


From: Henry Ptasinski <henryp at broadcom.com>

Move utility functions shared by the brcmsmac and brcmfmac drivers into a new
module, brcmutil.ko.  This eliminates the need to compile and link the shared
functions into both drivers.  Prefix all exported symbols with "bcm_".
