crypto: sahara - replace tasklets with kthread
In preparation for SHA support, replace the tasklets with a kthread that manages one crypto_queue for the core. As the Sahara can only process one AES or SHA request at a time, we make sure that the queue serializes all requests from userspace. Instead of a watchdog timer we now use a completion mechanism in the queue manager thread. This makes the control flow more obvious and guarantees, that only one request is dequeued until the completion is completed. Signed-off-by:Steffen Trumtrar <s.trumtrar@pengutronix.de> Signed-off-by:
