Subject: [PATCH] hw_random: mediatek: Setup default RNG quality
Date: Wed, 10 Jan 2018 12:02:46 +0800	[thread overview]
Message-ID: <134f98ae3270cc6040121cf75d50c916adfe58dc.1515556571.git.sean.wang@mediatek.com> (raw)

From: Sean Wang <sean.wang@mediatek.com>

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.
