I didn't know that the bug was severe and I applied the patch to ath-next, which means it will go to v5.5 which is bad. (This is why I always ask people to clearly describe the bug in the commit log!) In theory I could also push it to v5.4 but I just don't want to deal with the possible conflicts coming from duplicate commits. -- https://wireless.wiki.kernel.org/en/developers/documentation/submittingpatches
