Subject: [media] dvb: Initialize all cache values
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=26c924febc2a840fc232bfb3771df39810f5d362;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

[media] dvb: Initialize all cache values

By default, initialize the frontend current delivery system with
the first one. This warrants that a DVBv3 application will be able
to tune to it, after the removal of ops->init.type filling at
the drivers.
