From: Shiji Yang Date: Wed, 31 May 2023 02:50:04 +0000 (+0800) Subject: ath79: rename and sort patches by OpenWrt naming rules X-Git-Url: http://git.openwrt.org/?a=commitdiff_plain;h=c60dd7bef97772bfb7c23691986d71c17233553d;p=openwrt%2Fstaging%2Fnbd.git ath79: rename and sort patches by OpenWrt naming rules The patches in the ath79 target have not been sorted for a long time and they are very chaotic now. This patch sorts them again according to the OpenWrt naming rules[1], so that we can better manage them.
