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
