Hi Andy,
I've no idea what's happened with this patch[1], but it seems that it
were never applied. Is this patch still valid?

Thanks,

[RESEND] [PATCH for 2.6.37] cx23885, cx25840: Provide IR Rx timeout event reports
(Resending because Mauro reported losing some emails on IRC)
Provide CX2388[578] IR receive timeout (RTO) reports in the
final space raw event sent up the chain to the raw IR pulse
decoders. This should allow the lirc decoder to actually
measure the inter-transmission gap properly.
