[PATCH] KWorld UB435Q V3 (ATSC) tuner

[The Bit Pit <thebitpit@earthlink.net>]

>From Wilson Michaels <thebitpit@earthlink.net>

This patch fixes the KWorld UB435-Q V3 (ATSC) tuner functions:
1) The LED indicator now works.
2) Start up initialization is faster.
3) Add "lgdt330x" device name i2c_devs array used for debugging
4) Correct comments about the UB435-Q V3
