CIP testing did not find any problems here:

https://gitlab.com/cip-project/cip-testing/linux-stable-rc-ci/-/tree/linux-4.19.y

But reviews indicated two patches that are problematic in 4.19:

rc-v4.19.155.list: fd2278164808 o: | memory: emif: Remove bogus
debugfs error handling

- debugfs still returns NULL in 4.19 so this introduces bug. It is
just a cleanup so it can be reverted.

rc-v4.19.156.list: 7d5553147613 o: | drm/i915: Break up error capture
compression loops with cond_resched()

- code still needs to be atomic in 4.19; this probably depends on
a42f45a2a, see _object_create(). It does not fix anything severe so
it can be simply reverted.
