Most IR fixups take from:

http://git.kernel.org/?p=linux/kernel/git/jarod/linux-2.6-ir.git;a=shortlog;h=refs/heads/staging

Last three taken from:

http://git.linuxtv.org/jarod/linux-2.6-ir.git?a=shortlog;h=refs/heads/for-2.6.38

Should all be in v4l/dvb/rc soon...

    rc/streamzap: fix reporting response times
    
    The streamzap driver has relatively low sampling resolution, and any
    delays in reporting events seem to cause some minor problems for the
    likes of irw when using the lirc bridge driver, resulting in a single
    keypress registering as multiple independent ones, rather than as a
    single press with repeats. If we call ir_raw_event_handle() more
    frequently and reset the rawir kfifo at end-of-signal, the behavior
    improves quite a bit.

    mceusb: really fix remaining keybounce issues
    
    Make sure rawir struct is zeroed out before populating it for each
    ir_raw_event_store_with_filter() call, and when we see a trailing 0x80
    packet (end-of-data), issue an ir_raw_event_reset() call.

    ir-kbd-i2c: improve remote behavior with z8 behind usb
    
    Add the same "are you ready?" i2c_master_send() poll command to
    get_key_haup_xvr found in lirc_zilog, which is apparently seen in
    the Windows driver for the PVR-150 w/a z8. This stabilizes what is
    received from both the HD-PVR and HVR-1950, even with their polling
    intervals at the default of 100, thus the removal of the custom
    260ms polling_interval in pvrusb2-i2c-core.c.

    lirc_zilog: z8 on usb doesn't like back-to-back i2c_master_send
    
    Both the HD-PVR and HVR-1950, driven by the hdpvr and pvrusb2 drivers
    respectively, have a zilog z8 chip exposed via i2c. These are both
    usb-connected devices, and on both of them, back-to-back i2c_master_send
    calls that work fine with a z8 on a pci card fail with a -EIO, as the
    chip isn't yet ready from the prior command. To cope with that, add a
    delay and retry loop where necessary.

    We have to actually call i2c_new_device() once for each of the rx and tx
    addresses. Also improve error-handling and device remove i2c cleanup.

    tda829x: fix regression in probe functions
    
    In commit 567aba0b7997dad5fe3fb4aeb174ee9018df8c5b, the probe address
    for tda8290_probe and tda8295_probe was hard-coded to 0x4b, which is the
    default i2c address for those devices, but its possible for the device
    to be at an alternate address, 0x42, which is the case for the HVR-1950.
    If we probe the wrong address, probe fails and we have a non-working
    device. We have the actual address passed into the function by way of
    i2c_props, we just need to use it. Also fix up some copy/paste comment
    issues and streamline debug spew a touch. Verified to restore my
    HVR-1950 to full working order.
    
    Special thanks to Ken Bass for reporting the issue in the first place,
    and to both he and Gary Buhrmaster for aiding in debugging and analysis
    of the problem.

    mceusb: don't claim multifunction device non-IR parts
    
    There's a Realtek combo card reader and IR receiver device with multiple
    usb interfaces on it. The mceusb driver is incorrectly grabbing all of
    them. This change should make it bind to only interface 2 (patch based
    on lsusb output on the linux-media list from Lucian Muresan).
    
    Tested regression-free with the six mceusb devices I have myself.

    nuvoton-cir: fix wake from suspend
    
    The CIR Wake FIFO is 67 bytes long, but the stock remote appears to only
    populate 65 of them. Limit comparison to 65 bytes, and wake from suspend
    works a whole lot better (it wasn't working at all for most folks).
    
    Fix based on comparison with the old lirc_wb677 driver from Nuvoton,
    debugging and testing done by Dave Treacy by way of the lirc mailing
    list.
