[PATCH] fetch2: Don't show checksum warnings if a single checksum was supplied

[Richard Purdie <richard.purdie@linuxfoundation.org>]

If one checksum is supplied to a SRC_URI, we really don't want to show 
warnings about the other type which isn't present as one checksum
is really good enough for most cases.
