    Subject[PATCH 5.15 036/230] media: ir_toy: prevent device from hanging during transmit
    Date
    From: Sean Young <sean@mess.org>

    [ Upstream commit 4114978dcd24e72415276bba60ff4ff355970bbc ]

    If the IR Toy is receiving IR while a transmit is done, it may end up
    hanging. We can prevent this from happening by re-entering sample mode
    just before issuing the transmit command.
