[ 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")
