When IRQ HPD is simulated for DP MST, the driver updates the EDID in port context for all the ports in an effort to refresh the context with the new port count. But currently this operation is not synchronized with other debugfs operations and also the edid read operations on the existing port. This can cause the sim driver to update or delete the edid data while the edid data is being read on an existing port, which would result in an edid read failure on the DRM driver. This change synchronizes these operations to avoid these race conditions. Change-Id: I692af092583ed12b3da8c6587a74ec97d98fdfec Signed-off-by: Rajkumar Subbiah <quic_rsubbia@quicinc.com>
