    Subject[PATCH 5.15 296/846] regulator: qcom-labibb: OCP interrupts are not a failure while disabled
    Date
    From: Marijn Suijten <marijn.suijten@somainline.org>

    [ Upstream commit d27bb69dc83f00f86a830298c967052cded6e784 ]

    Receiving the Over-Current Protection interrupt while the regulator is
    disabled does not count as unhandled/failure (IRQ_NONE, or 0 as it were)
    but a "fake event", usually due to inrush as the is regulator about to
    be enabled.

    Fixes: 390af53e0411 ("regulator: qcom-labibb: Implement short-circuit and over-current IRQs")
