The kernel documentation file:
	https://www.kernel.org/doc/html/latest/process/submitting-patches.html
in section 2, describes how to show git ids within changelog text
properly (the number of characters and the rest.)

Can you fix this up and resend?

And this is a v2 patch, right?  Always document what changed from
previous patches below the --- line, as the above link asks for.

thanks,

greg k-h
