Subject: dmaengine: zx: fix build warning
From: Jun Nie <jun.nie@xxxxxxxxxx>
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':
