    Subject[PATCH v3 37/79] media: i2c: imx274: use pm_runtime_resume_and_get()
    Date
    Commit dd8088d5a896 ("PM: runtime: Add pm_runtime_resume_and_get to deal with usage counter")
    added pm_runtime_resume_and_get() in order to automatically handle
    dev->power.usage_count decrement on errors.

    Use the new API, in order to cleanup the error check logic.
