I noticed already a while ago that commit 020d3b26c07a ("bus: mhi: Early MHI resume failure in non M3 state"), introduced in v5.13-rc1, broke ath11k resume on my NUC x86 testbox using QCA6390. Interestingly enough Dell XPS 13 9310 laptop (with QCA6390 as well) does not have this problem, I only see the problem on the NUC. I do not know what's causing this difference.
