	platform_get_irq prints the error on failure, so there is no need to have caller add a log. Remove the log in uniphier_xdmac_probe() for platform_get_irq() failure Reported-by: kbuild test robot <lkp@intel.com> Link: https://lore.kernel.org/r/20200323171928.424223-1-vkoul@kernel.org Signed-off-by: Vinod Koul <vkoul@kernel.org>
2020-03-02	dmaengine: uniphier-xdmac: Add UniPhier external DMA controller driver	Kunihiko Hayashi
	This adds external DMA controller driver implemented in Socionext UniPhier SoCs. This driver supports DMA_MEMCPY and DMA_SLAVE modes. Since this driver does not support the the way to transfer size unaligned to burst width, 'src_maxburst' or 'dst_maxburst' of dma_slave_config must be 1 to transfer arbitrary size. If transfer size is unaligned to burst size, the transfer isn't started and the driver displays an error message.
