Looks to me the dependencies go the other way around (i.e. crypto
depends on LZO, not LZO on crypto):
-----------------
config CRYPTO_LZO
        tristate "LZO compression algorithm"
        select CRYPTO_ALGAPI
        select LZO_COMPRESS
        select LZO_DECOMPRESS
        help
          This is the LZO algorithm.
-----------------

So, one needs LZO_COMPRESS/DECOMPRESS for CYPTO_LZO. But, given we just
need straight compression/decompression, this should not be needed, if
I'm understanding things correctly.
