We have the ${target_branch}-external-fixes mechanism to merge necessary changes before building the kernel for CI. Which is necessary for a couple of reasons: 1) patches like this which aren't appropriate upstream but necessary due to the CI lab setup 2) target branch if often based on an early -rc, and it isn't unheard of to need some fix for some board or another which isn't appropriate to land via drm-next We should use the -external-fixes branch mechanism for patches like this one.
