Subject: [PATCH] dm integrity: select the Kconfig option CRYPTO_SKCIPHER
Date:   Mon, 14 Dec 2020 18:18:11 +0100

The integrity target relies on skcipher for encryption/decryption, but
certain kernel configurations may not enable CRYPTO_SKCIPHER, leading to
compilation errors due to unresolved symbols. Explicitly select
CRYPTO_SKCIPHER for DM_INTEGRITY, since it is unconditionally dependent
on it.
