From 50c546d70af866ea5cbeb39f5007df96ea27c41e Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Sun, 13 Aug 2023 14:54:24 +0800 Subject: [PATCH] crypto: jh1100 - Remove prepare/unprepare request The callbacks for prepare and unprepare request in crypto_engine is superfluous. They can be done directly from do_one_request. Move the code into do_one_request and remove the unused callbacks.
