Maybe that's related to wifi regdom, since wifi default area
was US and didn't support 12~14 channels.

I don't see how this fixes anything, care to explain? And the title is
quite vague.
Sorry for the description maybe unclear.
I'm assuming the print log is expected for marvel wifi driver. Do we
should use 'WARN' to instead of the 'ERROR' here.
But does that make any functional difference, isn't the warning still
printed?
At least, that shouldn't be printed log by default. :)
if I read the code is correct. That only the MSG/FATAL/ERROR will output
by default.
