Currently, cryptodev-linux fails to compile with a
'"crypto_givcipher_type" undefined' error for targets on the 5.4 kernel,
e.g. armvirt[1].
This backports an upstream patch[2] that fixes this error.

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:
 | 
						|
 | 
						|
