There are many cases of char foo[] = "bar" that
should be actually be [static] const char foo[] etc.
The patch set was done to change those cases.

This case isn't actually any sort of saving.

As I just wrote in 5/25 to Jonathan Cameron:

It tries to standardize the style use and it avoids possible
future checkpatch warnings of:
	char foo[] = "bar"
char array could possibly be static const.

There was another use with "%1.1d" somewhere.

The end result is the same, so I don't really care much
if this sort of change is applied or not.  The possible
checkpatch message could just be considered noise but
Mike Frysinger seemed to prefer it, so I thought I could
try to accommodate him.

cheers, Joe
