   4 Subject: [PATCH] brcmfmac: simplify building interface combinations
   5 MIME-Version: 1.0
   6 Content-Type: text/plain; charset=UTF-8
   7 Content-Transfer-Encoding: 8bit
   8
   9 Move similar/duplicated code out of combination specific code blocks.
  10 This simplifies code a bit and allows adding more combinations later.
  11 A list of combinations remains unchanged.
