Subject: mt76: remove offchannel check in tx scheduling
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=04824da9203d5056a93ab59247af2869e3fe7888;p=linux.git

mt76: remove offchannel check in tx scheduling

tx queues are already disabled by mac80211 during scanning or other
off-channel activity. There is no need to repeat the check in mt76,
since scheduled queues are selected by mac80211 as well.
