[PATCH] drm/msm: remove an unused-but-set variable

From: Arnd Bergmann
Date: Fri Apr 05 2024 - 11:59:08 EST


From: Arnd Bergmann <arnd@xxxxxxxx>

The modification to a6xx_get_shader_block() had no effect other
than causing a warning:

drivers/gpu/drm/msm/adreno/a6xx_gpu_state.c:843:6: error: variable 'out' set but not used [-Werror,-Wunused-but-set-variable]
u64 out = dumper->iova + A6XX_CD_DATA_OFFSET;

Revert this part of the previous patch.

Fixes: 64d6255650d4 ("drm/msm: More fully implement devcoredump for a7xx")
