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. Signed-off-by: Lee Jones <lee.jones@linaro.org> Acked-by: Peter Korsgaard <peter@korsgaard.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
