From decee2e8a9538ae5476e6cb3f4b7714c92a04a2b Mon Sep 17 00:00:00 2001 From: "Aleksandr V. Piskunov" Date: Sun, 2 Aug 2009 16:01:19 -0300 Subject: V4L/DVB (12485): zl10353: correct implementation of FE_READ_UNCORRECTED_BLOCKS Makes zl10353 a bit more DVB API compliant: FE_READ_UNCORRECTED_BLOCKS - keep a counter of UNC blocks FE_GET_FRONTEND - return last set frequency instead of zero Signed-off-by: Aleksandr V.
