Subject[PATCH] powerpc/powernv: fix a W=1 compilation warning
Date
The commit b575c731fe58 ("powerpc/powernv/npu: Add set/unset window
helpers") called pnv_npu_set_window() in a void function
pnv_npu_dma_set_32(), but the return code from pnv_npu_set_window() has
no use there as all the error logging happen in pnv_npu_set_window(),
so just remove the unused variable to avoid a compilation warning,

arch/powerpc/platforms/powernv/npu-dma.c: In function
'pnv_npu_dma_set_32':
arch/powerpc/platforms/powernv/npu-dma.c:198:10: warning: variable ‘rc’
set but not used [-Wunused-but-set-variable]
