[U-Boot] [PATCH] The type expected by %zd is ssize_t, but it was being passed a size_t.

[Mike Frysinger]

generally the subject/changelog should be more of the form:

cmd_nvedit: fix printf warning

gcc warns when using %zd with size_t types since the correct format is %zu:
  <insert gcc warning here>

otherwise, the change (in theory) makes perfect sense to me ... i
would ack if not for the commit summary/log ;)
