Subject: [PATCH 01/24] staging: ccree: remove ahash wrappers
Date: Tue, 12 Dec 2017 14:52:47 +0000 [thread overview]
Message-ID: <1513090395-7938-2-git-send-email-gilad@benyossef.com> (raw)
In-Reply-To: <1513090395-7938-1-git-send-email-gilad@benyossef.com>
Remove a no longer needed abstraction around ccree hash crypto API
internals that used to allow same ops to be used in synchronous and
asynchronous fashion.
