| Subject: ARM: shmobile: bockw: fixup DMA mask |
| |
| 4dcfa60071b3d23f0181f27d8519f12e37cefbb9 |
| (ARM: DMA-API: better handing of DMA masks for coherent allocations) |
| exchanged DMA mask check method. |
| Below warning will appear without this patch |
| |
| asoc-simple-card asoc-simple-card.0: \ |
| Coherent DMA mask 0xffffffffffffffff is larger than dma_addr_t allows |
| asoc-simple-card asoc-simple-card.0: \ |
| Driver did not use or check the return value from dma_set_coherent_mask()? |
