../drivers/gpu/drm/msm/adreno/a5xx_gpu.c:863:3: error: unknown field ‘show’ specified in initializer
../drivers/gpu/drm/msm/adreno/a5xx_gpu.c:863:11: error: ‘a5xx_show’ undeclared here (not in a function)
../drivers/gpu/drm/msm/adreno/a5xx_gpu.c:863:3: warning: excess elements in struct initializer [enabled by default]
../drivers/gpu/drm/msm/adreno/a5xx_gpu.c:863:3: warning: (near initialization for ‘funcs.base’) [enabled by default]
make[5]: *** [drivers/gpu/drm/msm/adreno/a5xx_gpu.o] Error 1
