From 4565da7c3995a07eea54b5e4a79d2c06209c0c85 Mon Sep 17 00:00:00 2001 From: Sean Wang Date: Wed, 10 Jan 2018 12:02:46 +0800 Subject: [PATCH] hwrng: mediatek - Setup default RNG quality When hw_random device's quality is non-zero, it will automatically fill the kernel's entropy pool at boot. For the purpose, one conservative quality value is being picked up as the default value.
