Yes, sorry about that. I wrongly assumed that the tools would do the correct
thing but I will make sure to build test before pushing in the future.

Huh that's a dangerous setting, I guess a dim patch to check for this and
very loudly complain would be good? Care to type that up? It's no big
deal because strange git settings for dim is pretty much a game of
whack-a-mole, but we should tackle them when they pop up.

Build testing before pushing should be done, not the other way round :-)
Also this is pretty much why we want gitlab CI and real branches.

[PATCH] drm: Fix build error caused by missing drm_nomodeset.o
The patch for commit ("6a2d2ddf2c34 drm: Move nomodeset kernel parameter
to the DRM subsystem") was generated with config 'diff.noprefix true'.
But later was applied using 'cat nomodeset.mbox | dim apply-branch' on a
machine with 'diff.noprefix false'. And command 'git am --scissors -3' as
used by the dim tool doesn't handle that case well, since the 3-way merge
wrongly resolves the path for new file drivers/gpu/drm/drm_nomodeset.c as
gpu/drm/drm_nomodeset.c instead.
It led to the following build error as reported by the kernel test robot:
make[4]: *** No rule to make target 'drivers/gpu/drm/drm_nomodeset.o', needed
by 'drivers/gpu/drm/built-in.a'.
Fixes: ("6a2d2ddf2c34 drm: Move nomodeset kernel parameter to the DRM
subsystem")
Reported-by: kernel test robot
