    Subject[PATCH 5.13 071/104] drm/msm/dp: use dp_ctrl_off_link_stream during PHY compliance test run
    Date
    From: Kuogee Hsieh <khsieh@codeaurora.org>

    [ Upstream commit 7591c532b818ef4b8e3e635d842547c08b3a32b4 ]

    DP cable should always connect to DPU during the entire PHY compliance
    testing run. Since DP PHY compliance test is executed at irq_hpd event
    context, dp_ctrl_off_link_stream() should be used instead of dp_ctrl_off().
    dp_ctrl_off() is used for unplug event which is triggered when DP cable is
    dis connected.

    Changes in V2:
    -- add fixes statement

    Fixes: f21c8a276c2d ("drm/msm/dp: handle irq_hpd with sink_count = 0 correctly")
