X-Git-Tag: firefly_0821_release~3680^2~2904^2~435
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=9b54464f16ae4f0a7ce14f384294ddb30c203a21;p=firefly-linux-kernel-4.4.55.git

[media] budget-ci: use DVBv5 parameters on set_params()

Instead of using DVBv3 parameters, rely on DVBv5 parameters to
set the tuner
