bad indentation ^^^   I would write it like this:

              (uri (string-append
                    "ftp://ftp.infradead.org/pub/mtd-utils/mtd-utils-"
                    version ".tar.bz2"))

'file-name' is not needed as the name of the source tarball is already
good enough.  It is needed, for example, when the source name does not
have a package name, like "v0.1.tar.gz" (the case of github tag
snapshots).

Also note that if 'file-name' would be required here, it should be ended
with ".tar.bz2": you rename it to "mtd-utils-1.5.2" and this is a bad
name for a "tar.bz2" file.

Please add #t in the end of this phase: a phase should return non-false
value if it succeeds.

It would be good if you write a comment before licenses, like what files
have what licenses.  Also is it really 'gpl2'?  If the license says "or
any later version", it should be 'gpl2+'.
