As per eudyptula challenge task 10 I had to fix coding styles. Thus I
used checkpatch.pl script and fixed a chunk of warnings and few errors.

Sir there were checkpatch.pl styling issues and I fixed them all
together, so should I write a proper changelog as what all I fixed i.e
errors and warnings thrown by checkpatch.pl

As the bot said, only do one type of thing per patch, and "fix all
checkpatch errors/warnings" is not one type of thing.

So should I send a fresh patch with minimal fixes? instead of replying
to this mail with [PATCH 01]

in another file.

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.
- 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

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.
- 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

As both drivers/staging/media/usbvision/Kconfig and .../TODO say, this
driver is deprecated and will be removed by the end of this year.
So don't bother with this driver.

Hans
