From: Tero Kristo <[email protected]> commit 0ecd89ec64116669bcf7f7feae03a110cc2ad30c from git://git.ti.com/ti-linux-kernel/ti-linux-kernel.git
Currently crypto_wait_req waits indefinitely for an async crypto request to complete. This is bad as it can cause for example the crypto test manager to hang without any notification as to why it has happened. Instead of waiting indefinitely, add a 1 second timeout to the call, and provide a warning print if a timeout happens.
