Subject: [PATCH 197/224] 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.
