Subject: [PATCH 05/12] crypto: caam - refactor RSA private key _done callbacks
Date: Mon, 18 Nov 2019 00:30:38 +0200 [thread overview]
Message-ID: <1574029845-22796-6-git-send-email-iuliana.prodan@nxp.com> (raw)
In-Reply-To: <1574029845-22796-1-git-send-email-iuliana.prodan@nxp.com>
Create a common rsa_priv_f_done function, which based
on private key form calls the specific unmap function.
