From 52ad252f9ecc9b83bd17b74280e10ae8fae15e44 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?=C3=8D=C3=B1igo=20Huguet?= Date: Fri, 21 Jan 2022 08:49:03 +0100 Subject: [PATCH 24/36] rtw89: remove cch_by_bw which is not used MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Bugzilla: http://bugzilla.redhat.com/2033291 commit c2258b29985eac9216a9e55f9d5bead9767f96da Author: Zong-Zhe Yang Date: Wed Dec 1 16:09:01 2021 +0800 rtw89: remove cch_by_bw which is not used Originally, cch_by_bw recorded center channels of each available bandwidths under current bandwidth. And the plan was to iterate cch_by_bw as parameters to query other configurations. However, we have not used it for the time being. Keeping it will disturb the follow-up things, such as bandwidth 160 MHz, so we remove it for now. If it's really needed at some point, we will redesign it.
