   4 Subject: [PATCH] brcmutil: print invalid chanspec when WARN-ing

   9 On one of my devices I got WARNINGs when brcmfmac tried to decode
  10 chanspec. I couldn't tell if it was some unsupported format or just a
  11 malformed value passed by a firmware.
  12
  13 Print chanspec value so it's possible to debug a possible problem.
