| Summary | "Out of range" on a display connected to a DVI-D output of RX460 card via DVI-D<=>HDMI-A cable |

I'm using the latest code from amd-staging-4.9 branch of ~agd5f/linux. The problem is caused by this commit: https://cgit.freedesktop.org/~agd5f/linux/commit/?h=amd-staging-4.9&id=2b2d4cfb0a629961a44e1ea0b29d336c1336deb9 After this change, when sink_signal is DVI_DUAL_LINK but pix_clk_khz is lower than TMDS_MAX_PIXEL_CLOCK_IN_KHZ, stream->signal is set to DVI_DUAL_LINK, while previously it was being set to DVI_SINGLE_LINK. As a result, the connected display just reports "Out of range" error.
