Hello,

I maintain a backport of patches from:
https://git.kernel.org/pub/scm/linux/kernel/git/kvalo/ath.git/log/drivers/net/wireless/ath

... to the 5.15.y stable kernel.

It looks like a recent set of patches for WoW broke QCN9074, but works fine on QCA6391. The error at boot on QCN9074 is failed to init wow: -22, as per below:
