dmesg of 2.6.37 (not working) kernel

The remote control of my TV card stopped working in kernel 2.6.37 (plain, from kernel.org).

The input device appears, but testing it with evtest shows no report of events on keypresses.

The card is a PCI "ASUSTeK P7131 Hybrid", attached to a 32-bit Pentium 4, using driver saa7134.

The remote works correctly in kernel 2.6.36.

Tried git-bisect and got the following result:
4651918a4afdd49bdea21d2f919b189ef17a6399 is the first bad commit

    [media] IR: extend ir_raw_event and do refactoring

    Add new event types for timeout & carrier report
    Move timeout handling from ir_raw_event_store_with_filter to
    ir-lirc-codec, where it is really needed.
    Now lirc bridge ensures proper gap handling.
    Extend lirc bridge for carrier & timeout reports

    Note: all new ir_raw_event variables now should be initialized
    like that: DEFINE_IR_RAW_EVENT(ev);
