    Subject[PATCH 5.4 019/355] media: ir-kbd-i2c: improve responsiveness of hauppauge zilog receivers
    Date
    From: Sean Young <sean@mess.org>

    commit c73ba202a851c0b611ef2c25e568fadeff5e667f upstream.

    The IR receiver has two issues:

    - Sometimes there is no response to a button press
    - Sometimes a button press is repeated when it should not have been

    Hanging the polling interval fixes this behaviour.
