Replaced sprintf() with sysfs_emit() in the protocol_id_show() sysfs attribute function. This code is safe, as replacing sprintf() with sysfs_emit() gets rid of calls to sprintf() as part of kernel hardening and sysfs_emit() is more appropriate in this context.

It's best to wait a day between resends.

I really hate to comment on this, because I famously get annoyed by people who act like it's soooo important and we have one "reviewer" who wants every sentence to be in imperative tense. But past tense is kind of ugly. You did it right in the Subject on v2. Use "Replace" instead of "Replaced" here as well.
Btw, if someone provides you a commit message, then they're basically obligated to allow it.
attribute function. This code is safe, as replacing sprintf() with

sysfs_emit() gets rid of calls to sprintf()
The line break is weird.
as part of kernel hardening and sysfs_emit() is more appropriate in this context.

Hi,
This is the friendly patch-bot of Greg Kroah-Hartman. 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
