Subject: [PATCH] UBUNTU: sms1xxx: fix invalid unc readings

OriginalAuthor: Michael Krufky <mkrufky at linuxtv.org>
OriginalLocation: http://linuxtv.org/hg/v4l-dvb/raw-rev/dfe767d471a1
Bug: #301405

Add function smsdvb_read_ucblocks to report uncorrectable error counts.
This is needed for the signal quality LEDs to function correctly.
