[PATCH v3 25/38] drm/msm/dp: Mark the SST bridge disconnected when mst is active

[Yongxing Mou]

From: Abhinav Kumar <quic_abhinavk at quicinc.com>

The bridge detect function is only applicable for SST. In MST mode,
connector detection is handled by MST bridges. This patch skips
detection for the SST bridge when MST is active.
