drm/amd/display: fix cursor black issue (c1cefe11) · Commits · 戴 / test

[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. Reviewed-by:
