3920631c4b [media] iguanair: do not modify transmit buffer
Since commit "[media] rc-core: move timeout and checks to lirc", the
incoming buffer is used after the driver transmits.

b83bfd1b01 [media] rc: do not wake up rc thread unless there is something to do
The TechnoTrend USB IR Receiver sends 125 ISO URBs per second, even when
there is no IR activity. Reduce the number of wake ups from the other
drivers too.

This saves about 0.25ms/s on a 2.4GHz Core 2 according to powertop.

640583836b [media] iguanair: fix receiver overflow
The Pioneer CU-700 remote causes receiver overflows if you hold down any
button. The remote does not send NEC IR repeats, it repeats the entire
NEC code after 20ms.

The iguanair hardware advertises an interval of 10 which just not enough;
with 100 URBs per second and at most 7 edges per URB, we handle at most
700 edges per second. The remote generates about 900.

2eec676cd3 [media] iguanair: advertise the resolution and timeout properly
With the timeout supplied the interface can go idle. The keymap is
the same one as other drivers which do not come with a remote.

supported. Also report the firmware version in the standard format.

urb callback we already have in place.
