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.

There is no rush with this one, it can wait for post 4.20 merge window.
