Subject: [media] stv090x: set status bits when there is no lock
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=4a6c4a9567aed23cf7e8134c63f3176a57e5572b;p=mv-sheeva.git

[media] stv090x: set status bits when there is no lock

Currently, the stv090x driver only set the status bits to SCVYL when
there is a lock. This patch set the right bits even if there is no lock.
