Subject: [PATCH 3/6] hwrng: imx-rngc - use devres for registration
Date: Tue, 28 Jan 2020 12:00:59 +0100 [thread overview]
Message-ID: <20200128110102.11522-4-martin@kaiser.cx> (raw)
In-Reply-To: <20200128110102.11522-1-martin@kaiser.cx>
Use devres to register the rngc with the hwrng core. Drop the explicit
deregistration.
