This is dropped patch, no need to be merged. We tested Atmel spi in your tree-next , but it doesn't work, the reason is the Joachim Eastwood's patch is not included. https://patchwork.kernel.org/patch/2165301/ which Joachim said that Grant said he applied. Thanks Best Regards, Wenyou Yang

Hi Wenyou, Sorry for not having communicating with you after Mark told me the story about this patch: Mark merged Grant's material in his SPI tree (with is the official one nowadays). You can see that by browsing linux-next: Merge remote-tracking branch 'spi/fix/grant' into spi-linus Joachim's patch is well included in it. We still have to monitor inclusion of it in Linus' tree... Mark, sorry for the noise. Bye,
