    Subject[PATCH 5.16 0278/1039] crypto: hisilicon/qm - fix incorrect return value of hisi_qm_resume()
    Date
    From: Weili Qian <qianweili@huawei.com>

    [ Upstream commit 3f9dd4c802b96626e869b2d29c8e401dabadd23e ]

    When hisi_qm_resume() returns 0, it indicates that the device has started
    successfully. If the device fails to start, hisi_qm_resume() needs to
    return the actual error code to the caller instead of 0.

    Fixes: d7ea53395b72 ("crypto: hisilicon - add runtime PM ops")
