There are old bttv-driven Hauppauge WinTV series cards that have
their IR part at i2c addr 0x71, which doesn't get considered in the
new 2.6.31 i2c code.

>From a 2.6.29 kernel:

lirc_i2c: chip 0x10005 found @ 0x71 (Hauppauge PVR150)

Minor cosmetic glitch, the card in question isn't actually a PVR-150, its:

03:06.0 Multimedia video controller: Brooktree Corporation Bt878 Video Capture 
(rev 11)
        Subsystem: Hauppauge computer works Inc. WinTV Series
        Flags: bus master, medium devsel, latency 32, IRQ 19
        Memory at f4ffe000 (32-bit, prefetchable) [size=4K]
        Capabilities: [44] Vital Product Data
        Capabilities: [4c] Power Management version 2
        Kernel driver in use: bttv
        Kernel modules: bttv

Device ID: 0x109e:0x036e, Sub-Device ID: 0x0070:0x13eb

This simply adds 0x71 to the list of addresses i2c_new_probed_device should
consider, which gets IR working on this card again.
