dmaengine: sh: make array ds_lut static
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@canonical.com> Link: https://lore.kernel.org/r/20210915112038.12407-1-colin.king@canonical.com Signed-off-by: Vinod Koul <vkoul@kernel.org>
