Subject: [PATCH 05/12] hwrng: bcm2835-rng: Use device managed helpers
Date: Wed, 1 Nov 2017 18:04:01 -0700 [thread overview]
Message-ID: <20171102010408.27736-6-f.fainelli@gmail.com> (raw)
In-Reply-To: <20171102010408.27736-1-f.fainelli@gmail.com>
Now that we have moved the RNG disabling into a hwrng::cleanup callback,
we can use the device managed registration operation and remove our
remove callback since it won't do anything necessary.
