Subject: iwlwifi: don't declare support for 5ghz if not supported
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=a76f3bfe016dbda161f9d31cc5cbdd9238d13488;p=linux-beck.git

iwlwifi: don't declare support for 5ghz if not supported

Remove a useless debug print about unsupported channels.
Also add a comment about the LAR special case where channels
might become valid later.
