Antti Palosaari 713d9b5d98 [media] af9015: remove 2nd I2C-adapter
It is useless. There is only one physical I2C-adapter.

2nd adapter was added originally due to some plans for allowing only one
demod to access bus at time. But I never implemented proper locking...

Juergen Lock 879b0d7957 [media] af9015: setup rc keytable for LC-Power LC-USB-DVBT
That's this tuner:

The credit card sized remote more or less works if I set remote=4,
so I added the hash to get it autodetected.  (`more or less' there
meaning sometimes buttons are `stuck on repeat', i.e. ir-keytable -t
keeps repeating the same scancode until i press another button.)

usb_control_msg initiates (and waits for completion of) a dma transfer using

the heap.
