DMA-API: media: omap3isp: use dma_coerce_mask_and_coherent()
The code sequence: isp->raw_dmamask = DMA_BIT_MASK(32); isp->dev->dma_mask = &isp->raw_dmamask; isp->dev->coherent_dma_mask = DMA_BIT_MASK(32); bypasses the architectures check on the DMA mask. It can be replaced with dma_coerce_mask_and_coherent(), avoiding the direct initialization of this mask.
