We observed the same WARN issue when loading the tcrypt module in a v5.15 kernel:

[   84.577572] modprobe tcrypt
[   84.920899] alg: skcipher: failed to allocate transform for ecb(cast5): -2
[   84.923050] ------------[ cut here ]------------
[   84.924541] alg: self-tests for ecb(cast5) (ecb(cast5)) failed (rc=-2)
[   84.924557] WARNING: CPU: 0 PID: 3910 at crypto/testmgr.c:5681 alg_test+0x344/0x5d8

This patch fixes this issue.
