+Subject: [PATCH] Fix module loading with Linux v5.0-rc5
+
+This commit fixes this module load error:
+[...]
+[   29.112091] cryptodev: loading out-of-tree module taints kernel.
+[   29.128906] cryptodev: Unknown symbol crypto_givcipher_type (err -2)
+[   29.188842] cryptodev: Unknown symbol crypto_givcipher_type (err -2)
+modprobe: can't load module cryptodev (extra/cryptodev.ko): unknown symbol in module, or unknown parameter
+[...]
+
+Upstream Linux support for unused GIVCIPHER, and others, was dropped here:
+
+c79b411eaa72 (crypto: skcipher - remove remnants of internal IV generators)
