Subject: [PATCH] cfg80211: fix boundary value in ieee80211_frequency_to_channel()
Date: Tue,  3 Sep 2019 13:39:32 +0200	[thread overview]
Message-ID: <1567510772-24263-1-git-send-email-arend.vanspriel@broadcom.com> (raw)

The boundary value used for the 6G band was incorrect as it would
result in invalid 6G channel number for certain frequencies.
