Again, that kernel tree will go out of support in 3 days from us, so not much we can do here, you should seriously consider upgrading as you are going to have a very insecure system soon (not to mention that the latest 5.4.y release, 5.4.301, currently has 1541 unfixed CVEs in it...) thanks, greg k-h
