Chenyuan Yang 7a2ca2ea64 drm/amd/display: Add null pointer check in mod_hdcp_hdcp1_create_session() ... The function mod_hdcp_hdcp1_create_session() calls the function get_first_active_display(), but does not check its return value. The return value is a null pointer if the display list is empty. This will lead to a null pointer dereference. Add a null pointer check for get_first_active_display() and return MOD_HDCP_STATUS_DISPLAY_NOT_FOUND if the function return null. This is similar to the commit c3e9826a22 ("drm/amd/display: Add null pointer check for get_first_active_display()").
