I have reproduced this.

So I compared the before/after on intermediate files

sdiff -lw300 drivers/gpu/drm/drm_print.i \

../../../wk-test/builds/parisc-1/drivers/gpu/drm/drm_print.i | less +/static_branch

and the obvious thing is the header include is much earlier in the broken version.

so I moved the include down and out to drm_print.h

this fixed the immediate problem, so I'm rerolling

for another run through lkp-test
