Subject: [PATCH] cfg80211: fix boundary value in ieee80211_frequency_to_channel()
Git-commit: df5d7a88bc9409aff60f67d82ee25715fa48a22d
Patch-mainline: v5.4-rc1
References: jsc#SLE-13430
The boundary value used for the 6G band was incorrect as it would
result in invalid 6G channel number for certain frequencies.
