Subject: crypto: crypto_wq - Fix late crypto work queue initialization
From: Tim Chen <tim.c.chen@xxxxxxxxxxxxxxx>
commit 130fa5bc81b44b6cc1fbdea3abf6db0da22964e0 upstream.
The crypto algorithm modules utilizing the crypto daemon could
be used early when the system start up. Using module_init
does not guarantee that the daemon's work queue is initialized
when the cypto alorithm depending on crypto_wq starts. It is necessary
to initialize the crypto work queue earlier at the subsystem
init time to make sure that it is initialized
when used.
