+Subject: [PATCH] brcmutil: print invalid chanspec when WARN-ing
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+On one of my devices I got WARNINGs when brcmfmac tried to decode
+chanspec. I couldn't tell if it was some unsupported format or just a
+malformed value passed by a firmware.
+
+Print chanspec value so it's possible to debug a possible problem.
