Subject: [RFC PATCH] crypto: zlib-deflate - add zlib-deflate test case in tcrypt
Date:   Fri, 27 Sep 2019 11:05:15 +0800

As a type CRYPTO_ALG_TYPE_ACOMPRESS is needed to trigger crypto acomp test,
we introduce a new help function tcrypto_test_extend to pass type and mask
to alg_test.

Then tcrypto module can be used to do basic acomp test by:
insmod tcrypto.ko alg="zlib-deflate" mode=55 type=10
