+Subject: [PATCH 1730/2940] drm/amd/display: fix cursor black issue
+
+[Why]
+the member sdr_white_level of struct dc_cursor_attributes was not
+initialized, then the random value result that
+dcn10_set_cursor_sdr_white_level() set error hw_scale value 0x20D9(normal
+value is 0x3c00), this cause the black cursor issue.
+
+[how]
+just initilize the obj of struct dc_cursor_attributes to zero to avoid
+the random value.
