Subject: Re: [PATCH v2 1/7] drm/msm/dp: use dp_ctrl_off_link_stream during PHY
 compliance test run

Quoting Kuogee Hsieh (2021-07-13 08:54:01)
> 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")
