I did some randconfig testing on 5.10.y and the following patches are required.
d7a7d721064c5 ("media: ti-vpe: cal: avoid FIELD_GET assertion") 42d95d1b3a9c6 ("drm/rcar: stop using 'imply' for dependencies")
The first patch is only required on 5.10.y. The second "drm/rcar" commit is required in 5.15.y as well.
I'm going to be doing regular randconfig testing on stable so let me know if you have any advice.
