Also replace this comment with a FIXME comment: /* Do DMA mapping "early" for better error reporting and * dcache use. Note that if dma_unmap_single() ever starts * to do real work on ARM, we'd need to clean up mappings * for previous transfers on *ALL* exits of this loop... */ as the comment is not true - we do work in dma_unmap() functions, particularly on ARMv6 and above. I've corrected the existing unmap functions but if any others are required they must be added ASAP.

The test "if (spi_imx->irq <= 0)" is not testing the IRQ value, but the return value of platform_get_irq(). As platform_get_irq() can return an error (-ENXIO) or the IRQ value it found, the test should be "if (spi_imx->irq < 0)" [grant.likely: Note: In general, Linux irq number 0 should also mean no irq, but arm still allows devices to be assigned 0, and the imx platform uses 0 for one of the spi devices, so this patch is needed for the device to work] Signed-off-by: NRichard Genoud <richard.genoud@gmail.com> Signed-off-by: NGrant Likely <grant.likely@secretlab.ca>
