Subject: [PATCH v2 12/12] lgdt3306a: Add CNR v5 stat
Date: Wed, 27 Feb 2019 12:27:46 -0600 [thread overview]
Message-ID: <1551292066-29574-13-git-send-email-brad@nextdimension.cc> (raw)
In-Reply-To: <1551292066-29574-1-git-send-email-brad@nextdimension.cc>
The CNR is already calculated, so populate DVBv5 CNR stat
during read_status.
