This was added in 5.4 with this commit :
https://github.com/torvalds/linux/commit/bfc4c359b2822bd2c457ccab271baeb33181c7c9#diff-0f28900cd4f7f14731c970ed828f4e53
But you should be able to use drm-devel-kmod and backport this patch.
I'm working on 5.4 but won't have something until next week I think.
