You have sent him a patch that has triggered this response. He used to manually respond to these common problems, but in order to save his sanity (he kept writing the same thing over and over, yet to different people), I was created. Hopefully you will not take offence and will fix the problem in your patch and resubmit it so that it can be accepted into the Linux kernel tree. You are receiving this message because of the following common error(s) as indicated below: - This looks like a new version of a previously submitted patch, but you did not list below the --- line any changes from the previous version. Please read the section entitled "The canonical patch format" in the kernel file, Documentation/process/submitting-patches.rst for what needs to be done here to properly describe this. If you wish to discuss this problem further, or you have questions about how to resolve this issue, please feel free to respond to this email and Greg will reply once he has dug out from the pending patches received from other developers. thanks, greg k-h's patch email bot

The information within [] is redundant and should be removed 2. Regarding your question, before submitting the patch, I conducted the following tests: 1) linux + x86: The SanDisk Extreme Pro 55AF device can be recognized normally when using the uas driver. USB controller model (VendorID: 1D94, DeviceID: 145F,Chengdu Haiguang IC Design Co., Ltd.USB 3.0 Host controller) 2) linux + arm64: The SanDisk Extreme Pro 55AF device will report an error when using the uas driver and the driver cannot be loaded. USB Controller model (Vendor ID: 1912, Device ID: 0014,uPD720201 USB 3.0 Host Controller). 3) linux + arm64: Add the parameter "USB-storage.quirks =0781:55af:u" in grub. The SanDisk Extreme Pro 55AF device runs the usb storage driver without any error and can be recognized normally.

What happens? > 3) linux + arm64: Add the parameter "USB-storage.quirks =0781:55af:u" in > grub. > The SanDisk Extreme Pro 55AF device runs the usb storage driver without any > error > and can be recognized normally. Let's track down and fix the arm64 issue here please, and not paper over it by saying that this whole device will not work well on all arches. thakns, greg k-h

The V2 patch sent for the second time only adds a description of the differences from the V1 patch compared to the V2 patch sent for the first time. There is no modification to the code. So it is rashly believed that it does not need to be defined as a V3 patch.
