After testing this patch with the test application by simply executing 
[1]/test/test.sh, the hash and skcipher interface invocation hang in kernel 
space. Though, I am not sure where the problem is.

For individual invocations of the tests, you may look into [1]/test/kcapi-
main.c in the comments above cavs_sym or cavs_hash.
