Add comments describing what the lock fields in struct gb_tty protect, and fix the indentation of the wait_for_completion_timeout() call.

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:

- 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.

- 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,
