    Subject[PATCH 5.10 441/563] crypto: omap-aes - Fix broken pm_runtime_and_get() usage
    Date
    From: Heiner Kallweit <hkallweit1@gmail.com>

    commit c2aec59be093bd44627bc4f6bc67e4614a93a7b6 upstream.

    This fix is basically the same as 3d6b661330a7 ("crypto: stm32 -
    Revert broken pm_runtime_resume_and_get changes"), just for the omap
    driver. If the return value isn't used, then pm_runtime_get_sync()
    has to be used for ensuring that the usage count is balanced.

    Fixes: 1f34cc4a8da3 ("crypto: omap-aes - Fix PM reference leak on omap-aes.c")
