Also in:
imx, linux-arm-kernel, linux-pci, lkml
+ /* set 64-bit DMA mask and coherent DMA mask */ + ret = dma_set_mask_and_coherent(dev, DMA_BIT_MASK(64));
The comment is a bit silly :)
+ if (ret) + return ret;
Also no need to check the return value when setting a 64-bit mask, but I guess it desn't hurt here.
