From d9a53b01404fa602117220e98bb6c9b2b63f1e7f Mon Sep 17 00:00:00 2001 From: Lee Jones Date: Thu, 17 Sep 2015 14:45:53 +0100 Subject: [PATCH] hwrng: core - Simplify RNG switching from sysfs If we attempt to use sysfs to change the current RNG in the usual way i.e. issuing something like: `echo 8a8a000.rng > /sys/devices/virtual/misc/hw_random/rng_current` ... it will fail because the code doesn't currently take the '\n' into consideration. Well, now it does.
