Steps to reproduce:

$ wget https://downloads.openwrt.org/releases/21.02.0/targets/ipq40xx/generic/openwrt-21.02.0-ipq40xx-generic-plasmacloud_pa1200-squashfs-factory.bin
$ binwalk -e openwrt-21.02.0-ipq40xx-generic-plasmacloud_pa1200-squashfs-factory.bin
$ ls -ltr _openwrt-21.02.0-ipq40xx-generic-plasmacloud_pa1200-squashfs-factory.bin.extracted/squashfs-root/lib/firmware/ath10k/QCA4019/hw1.0/board-2.bin

But expected were (on tag v21.2.0):

$ ls -ltr package/firmware/ipq-wifi/board-plasmacloud_pa1200.qca4019
-rw-r--r-- 1 sven sven 24324 Aug 17 09:23 package/firmware/ipq-wifi/board-plasmacloud_pa1200.qca4019
$ md5sum package/firmware/ipq-wifi/board-plasmacloud_pa1200.qca4019
73129ba35258a8505407364ecedc13ec package/firmware/ipq-wifi/board-plasmacloud_pa1200.qca4019

This breaks wifi on some devices but can also damage them.
