The Owl Loader (named after the codename that Atheros gave these devices back in the day) has been accepted upstream. This patch removes the "misc" driver OpenWrt had and adds the remaining differences against the version that ships with 5.4-rc1 into a separate "120-owl-loader-compat.patch" file that can be cut down once AR71XX is being dealt with. Note: I decided to keep the existing (kmod-)owl-loader package name around for now. The kernel module file in the kmod package will be called ath9k_pci_owl_loader.ko though.
