[PATCH 5.10.y-cip 20/22] dmaengine: sh: make array ds_lut static
Lad Prabhakar
From: Colin Ian King <colin.king@...>
commit 4c0eee50658746b0333d35a75d3db6e0aac08ef9 upstream. Don't populate the read-only array ds_lut on the stack but instead it static. Also makes the object code smaller by 163 bytes: Before: text data bss dec hex filename 23508 4796 0 28304 6e90 ./drivers/dma/sh/rz-dmac.o After: text data bss dec hex filename 23281 4860 0 28141 6ded ./drivers/dma/sh/rz-dmac.o (gcc version 11.2.0) Signed-off-by: Colin Ian King <colin.king@...> Link: https://lore.kernel.org/r/20210915112038.12407-1-colin.king@canonical.com Signed-off-by: Vinod Koul <vkoul@...> Signed-off-by: Lad Prabhakar <prabhakar.mahadev-lad.rj@...> --- drivers/dma/sh/rz-dmac.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/dma/sh/rz-dmac.c b/drivers/dma/sh/rz-dmac.c index d9f2cfef878e..ee2872e7d64c 100644 --- a/drivers/dma/sh/rz-dmac.c +++ b/drivers/dma/sh/rz-dmac.c @@ -574,7 +574,7 @@ static void rz_dmac_issue_pending(struct dma_chan *chan) static u8 rz_dmac_ds_to_val_mapping(enum dma_slave_buswidth ds) { u8 i; - const enum dma_slave_buswidth ds_lut[] = { + static const enum dma_slave_buswidth ds_lut[] = { DMA_SLAVE_BUSWIDTH_1_BYTE, DMA_SLAVE_BUSWIDTH_2_BYTES, DMA_SLAVE_BUSWIDTH_4_BYTES, -- 2.17.1
