   text	   data	    bss	    dec	    hex	filename
   6798	   2848	      4	   9650	   25b2	drivers/usb/core/sysfs.o

File size After adding 'const':
   text	   data	    bss	    dec	    hex	filename

You have sent a lot of these types of patches out, and really, this is a
horrible changelog entry.  You are assuming that I know what this is,
and why it is a good thing.  Now I might, but maybe not...

Please actually explain why you are making this change.  Why it is
needed.  And big hint, it's not only about the output of the file
size...

Please fix this up for all of the patches you have sent me in this
format, as I'm deleting them all from my queue right now.

thanks,
