Hi
Occassionally, but not readily reproducably, I hit a race condition
between mceusb and other connected RC_CORE devices when mceusb tries
to create /class/rc/rc0, which is -by then- already taken by another
RC_CORE device. The other involved IR devices (physically only one)
are part of a PCIe TeVii s480 s2.1 twin-tuner DVB-S2 card and aren't
actually supposed to receive IR signals (IR receiver not connected):
mceusb device transceiver:
Bus 002 Device 004: ID 0609:0334 SMK Manufacturing, Inc. eHome Infrared Receiver
DVB-T receiver (no RC_CORE device)

twin-tuner DVB-S2 PCIe device, TeVii s480 v2.1 (physically one IR
receiver (NEC protocol), logically recognized as two RC_CORE devices):

Today I got a new, similar, trace with kernel 3.18.1, but this is not a
regression and randomly happens with older kernels as well. The
frequency of this occuring differs vastly, this time it was 12 days
with probably 20 (re-)boots, before that it didn't happen for multiple
weeks. I can not totally rule out if it ever happened in the reverse
detection/ initialisation order, as I wouldn't notice the consequences
of dvb_usb_dw2102's RC_CORE devices failing to initialise, but I think
the problem might be seated in the common core of rc-main.c.
