In commit d68b295 ("dm crypt: use GFP_ATOMIC when allocating crypto requests
from softirq") I wrongly copy pasted crypto request allocation code from
crypt_alloc_req_skcipher to crypt_alloc_req_aead. It is OK from runtime
perspective as both simple encryption request pointer and AEAD request pointer
are part of a union, but may confuse code reviewers.
Fixes: d68b295 ("dm crypt: use GFP_ATOMIC when allocating crypto requests from softirq")
