This patch appears to be fixing the whitespace issues introduced by your 
previous patch of the same name, but your previous patch hasn't been 
applied because of the whitespace issues.

What you need to do in this case is merge this patch with your previous 
of the same name, for example by using an interactive git rebase with 
this patch marked as a 'fixup' patch.  Then submit the combined single 
patch using the '[PATCH v2]' tag in the email.

If that's a bit daunting, it might be easier for you to recreate the 
patch from scratch!
