You will only see this when building in-tree (i.e., no O= or
KBUILD_OUTPUT) because $(src) and $(obj) are only added to the include
path automatically when building out of tree (see scripts/Makefile.lib,
search for 'ifdef building_out_of_srctree'), which could explain why you
(and presumably Mark doing -next) have not seen this error yet.
$ make -skj"$(nproc)" ARCH=arm64 CROSS_COMPILE=aarch64-linux- O=build
defconfig drivers/gpu/drm/panthor/panthor_gpu.o
$ make -skj"$(nproc)" ARCH=arm64 CROSS_COMPILE=aarch64-linux- defconfig
drivers/gpu/drm/panthor/panthor_gpu.o
