Subject: V4L/DVB (9180): S2API: Added support for DTV_CODE_RATE_HP/LP
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=a4de91be46b73ec6743b9d76155550e49507723c;p=openwrt%2Fstaging%2Fblogic.git

V4L/DVB (9180): S2API: Added support for DTV_CODE_RATE_HP/LP

Reports from users that using the new API for tuning DTV was failing,
and the cache was missing some essential items.
