 I did a quick test and only two commits needs to be back-out to have
v5.4.58 :

 https://github.com/torvalds/linux/commit/f14f27b1663269a81ed62d3961fe70250a1a0623
 https://github.com/torvalds/linux/commit/873a95e0d59ac06901ae261dda0b7165ffd002b8

 I'll look at what's really needed in a few days.

 I've pushed a 5.4-lts branch
https://github.com/freebsd/drm-kmod/tree/5.4-lts

 This has not been tested yet (just compiled).
