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]
