dmaengine: zx: fix build warning
commit 067fdeb2f391bfa071f741a2b3eb74b8ff3785cd upstream. Fix build warning that related to PAGE_SIZE. The maximum DMA length has nothing to do with PAGE_SIZE, just use a fix number for the definition. drivers/dma/zx_dma.c: In function 'zx_dma_prep_memcpy': drivers/dma/zx_dma.c:523:8: warning: division by zero [-Wdiv-by-zero] drivers/dma/zx_dma.c: In function 'zx_dma_prep_slave_sg': drivers/dma/zx_dma.c:567:11: warning: division by zero [-Wdiv-by-zero] Signed-off-by: Jun Nie <jun.nie@linaro.org> Tested-by: Shawn Guo <shawn.guo@linaro.org> Signed-off-by: Vinod Koul <vinod.koul@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
