Subject: [PATCH v6 4/9] crypto: caam - refactor RSA private key _done callbacks
Date: Wed, 12 Feb 2020 19:55:19 +0200	[thread overview]
Message-ID: <1581530124-9135-5-git-send-email-iuliana.prodan@nxp.com> (raw)
In-Reply-To: <1581530124-9135-1-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.
