Hi Greg, I realised several things. Firstly, when I initially contacted you, it was simply based on looking up who maintained drivers/net/usb in the MAINTAINERS file, however when running scripts/get_maintainer.pl, I realise that there are many other people who maintain drivers/net/usb/r8152.c. Should I include them in future submissions? Or should I just stick to you for now? Secondly, running scripts/checkpatch.pl on Realtek's code gives many warnings and errors. E.g. the code is written to be compatible for old versions of the kernel, whereas checkpatch.pl insists that each kernel version should have dedicated code for itself. I am hesitant to edit the original code more than I already have, but if necessary, I can make another patch when I resubmit to iron out all the trivial style issues. However I may need some guidance, e.g. on the use of the volatile keyword; since I am not the original developer, it will be difficult for met to judge whether its usage is critical for the code. Thirdly, if I do remove all of the macros for backwards compatibility, (# if LINUX_VERSION_CODE >= KERNEL_VERSION(a,b,c)), it will be difficult for distros like Ubuntu to incorporate the updated module into their older kernels. How can the version-two module also be included in the other stable/longerm kernels? Best, From Albert Zhou On 5/11/22 01:40, Greg KH wrote:

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: - Your patch contains warnings and/or errors noticed by the scripts/checkpatch.pl tool. - Your patch does not have a Signed-off-by: line. Please read the kernel file, Documentation/SubmittingPatches and resend it after adding that line. Note, the line needs to be in the body of the email, before the patch, not at the bottom of the patch or in the email signature. - Your patch did many different things all at once, making it difficult to review. All Linux kernel patches need to only do one thing at a time. If you need to do multiple things (such as clean up all coding style issues in a file/driver), do it in a sequence of patches, each one doing only one thing. This will make it easier to review the patches to ensure that they are correct, and to help alleviate any merge issues that larger patches can cause. - You did not specify a description of why the patch is needed, or possibly, any description at all, in the email body. Please read the section entitled "The canonical patch format" in the kernel file, Documentation/SubmittingPatches for what is needed in order to properly describe the change. - You did not write a descriptive Subject: for the patch, allowing Greg, and everyone else, to know what this patch is all about. Please read the section entitled "The canonical patch format" in the kernel file, Documentation/SubmittingPatches for what a proper Subject: line should look like. 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
