Hi,

In today's next, I got:

    drivers/gpu/drm/msm/adreno/a6xx_gpu_state.c:843:6: error: variable
'out' set but not used [-Werror,-Wunused-but-set-variable]

`out` seems to be there since commit 64d6255650d4 ("drm/msm: More
fully implement devcoredump for a7xx").

Untested diff below assuming `dumper->iova` is constant -- if you want
a formal patch, please let me know.

Cheers,
Miguel
