    Subject[PATCH 4.14 086/115] drm/i915/lpe: Mark LPE audio runtime pm as "no callbacks"
    Date
    4.14-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Chris Wilson <chris@chris-wilson.co.uk>

    commit 75eef0f1ed478284911b8723a5bdb659499a7aac upstream.

    The LPE audio is a child device of i915, it is powered up and down
    alongside the igfx and presents no independent runtime interface. This
    aptly fulfils the description of a "No-Callback" Device, so mark it
    thus.

    Fixes: 183c00350ccd ("drm/i915: Fix runtime PM for LPE audio")
    Testcase: igt/pm_rpm/basic-pci-d3-state
    Testcase: igt/pm_rpm/basic-rte
