modprobe si21xx debug=1 produces this output when scanning.

Since the tuner at hand uses a Si2109 chip, VSTATUS 0x01 and 0x02 would
indicate that blind scanning is used. Blind scanning is a 2109/2110
specific function, and may not very usable since we always use initial
tuning files anyway. 2109/10 also supports the legacy scanning method
which is supported by Si2107708.
Is the use of blind scanning intentional?
